Daily Precipitation Record Broken…

Afternoon thunderstorms have produced 1.23 inches of rain in Okarche which has brought the monthly total up to 4.07 inches.  When we started the day, this was the 11th wettest July in Okarche.  We have now jumped up to 6th place on the list.  We are also now only 1.40 inches from having the wettest July on record.

Also, today marks the 6th day in a row for measurable precipitation which ties the record for the 8th most.

The 1.23 inches of rain so far today breaks the old record of 0.39 of an inch set in 1993.

Cool and Wet – Flash Flooding Possible as records start to fall…

All of the first six days of July have seen below normal temperatures in Okarche.  Low high temperature records were set on the 3rd and 4th.

On the precipitation front… a total of 2.84 inches of rain has fallen over five consecutive days (2nd-6th).  Rain today would result in the six days of consecutive days of precipitation being in a tie for 8th ever.  Rain on Thursday would result in a tie for 3rd (seven days).  Rain on Friday would tie for first at eight consecutive days.

The total precipitation of 1.35 inches on the 5th was a record for the date.  We have had enough rainfall to start looking at July records:

1 – 2007 / 5.47

2 – 1996 / 4.92

3 – 2005 / 4.62

4 – 2006 / 4.60

5 – 1997 / 4.56

6 – 1991 / 4.00

7 – 1995 / 3.79

8 – 1999 / 3.54

9 – 1989 / 3.50

10 – 1987 / 3.20

11 – 2010 / 2.84

So, we sit in 11th place overall for the month of July, but only a little over 2 1/2 inches from 1st place.  Not only is it still very early in the month… a Flash Flood Watch is in effect for today, Thursday and Friday.  Given the very tropical nature of the atmosphere, it becomes very easy to believe that 2 to 3 inches of rain could fall during the next couple of days.

As far as the heat goes…. well it has to go somewhere…. and it did!  To the northeast where record temperatures have been falling over the last few days.

From Bloomberg Businessweek:

July 7 (Bloomberg) — New York City temperatures may reach 100 degrees again today after setting a new daily record and coming within 3 degrees of an all-time high, the National Weather Service said.

While today’s readings aren’t forecast to reach yesterday’s 103 Fahrenheit (39 Celsius), most people won’t feel much relief from the heat wave that began over the weekend, said Richard Castro, a weather service meteorologist in Upton, New York.

“It will still be extremely hot,” Castro said by telephone. “Cooling off a couple of degrees from temperatures in the 100s isn’t relief.”

Above-average temperatures will hang on through the week and Washington may see its hottest day today, said Joe Bastardi, chief meteorologist at AccuWeather Inc. in State College, Pennsylvania.

U.S. nuclear production rose to the highest level in at least 17 years, 98,740 megawatts, as the heat wave boosted demand for electricity, the Nuclear Regulatory Commission reported.

Utilities asked customers to curb electricity use as the high temperatures from Virginia to Maine strained air conditioners and raised power use in New York to 33,450 megawatts, just below the record of 33,939 set in August 2006, according to the New York Independent System Operator.

Conservation Urged

Consolidated Edison Co. urged its customers in the New York City area to conserve power during the day. The company reduced voltage to several Queens and Brooklyn neighborhoods by 5 to 8 percent last night and this morning because of problems with electrical cables.

About 375,400 customers in those neighborhoods, which included Flushing, Gowanus, Forest Hills and Brooklyn Heights among others, were affected. About 6,934 ConEd customers are without power in the metropolitan area, according to company outage maps.

In Rhode Island, the heat overloaded the electric grid, which is still damaged from flooding in March, according to National Grid. The company shut power down intermittently to about 1,600 customers, according to a statement on its website.

“With temperatures approaching 100 degrees yesterday and today, the local system in its compromised state simply cannot handle the demand being placed upon it,” the statement said.

The weather service is predicting Washington and Baltimore will reach 102 today. Yesterday, Reagan Washington National Airport recorded 102 and Baltimore-Washington International posted a mark of 105 degrees.

Eastern Swelter

Heat advisories and air quality alerts stretch from Virginia through New York and Vermont to Canada, where temperatures in Montreal hit the 90s yesterday, according to the weather service.

Heat advisories mean the high temperatures may have serious health consequences while air quality advisories warn that pollution and ground level ozone will be dangerous for people with breathing problems.

An excessive heat warning has been issued for Philadelphia, eastern Pennsylvania and parts of New Jersey and Delaware. While temperatures in the area aren’t supposed to be as high as yesterday, there will be greater humidity, making it feel just as hot, the weather service said in a statement.

A heat wave is defined as at least three days in a row of temperatures of 90 or more, and temperatures in New York reached the upper 90s on July 4. New York’s last weeklong heat wave was in August 1998, while the longest was 12 days from Aug. 24 to Sept. 4, 1953, according to agency records.

NYC Record

The longest stretch of consecutive 100-plus days on record at Central Park came in 1993, when it rose from 100 on July 8 to 102 on July 10.

A daily record high temperature of 102 degrees was set at T.F. Green International Airport in Warwick, Rhode Island, breaking the mark of 97 set in 1999, according to the weather service.

A record high temperature of 102 degrees was also set at Bradley International Airport in Windsor Locks, Connecticut, breaking the old mark for the day of 99 in 1999, the weather service said.

Bastardi said while temperatures will start to fall by the weekend, he expects July will be much warmer than normal across most of the country. He said another heat wave will probably arrive after July 15 and bring temperatures of 100 or higher to the northern Great Plains and Chicago.

“I don’t think this is the last of the heat,” Bastardi said in an interview. “The next time it comes back it may not be as extreme on the East Coast, but the Northern Plains, Chicago and Minneapolis are liable to broil for the last two weeks of July.”

Castro said the high temperatures in New York will only be in the 90s as the week goes on and by the weekend will be in the high 80s. He said normal high temperatures for this time of year are in the 80s.

Yesterday the weather service issued heat advisories for much of the East and Northeast, meaning the high temperatures may have serious health consequences.

In addition to the heat, air quality advisories warned that pollution and ground level ozone will be dangerous today, especially for people with breathing problems.

July 5th Sunset – Without Fireworks!

The moist atmosphere… clouds and showers/thunderstorms that we have been blessed with over the past couple of weeks have provided us with rainfall that you never turn down this time of year.  The added benefit has been some amazing sunsets… and once again, the sunset on July 5th didn’t disappoint.

A small line of thunderstorms was moving into Kingfisher County, and we set out with the hope of a few lightning photos.  While lightning was very minimal at best, the sunset was great and made the short trip worthwhile!

July Rain and Fireworks!

4 [800x600]

As strange of year weatherwise we have had thus far, it should not seem odd to be getting the July we are at the current time.  We have seen rainfall in Okarche four out of five days and nearly have two inches to show for it this month.  Today’s rain has just hit 0.91 of an inch which sets a record for July 5th.  It has also kept things nice and cool for the most part with all days so far below normal on temperature.

The break in the rain on the 4th came at just the right time for an evening of “blowing stuff up”.  A great time was had by all…

1 [800x600] 2 [800x600] 3 [800x600]

This and That…

First… another wonderful sunset on the 27th:

1 [800x600]

Rainfall was spotty over the last week, but some places did end up with a good amount.  Okarche was on the lower end of things coming in at 0.58 of an inch.  Northwest Oklahoma missed out the most:

50

After a long stretch of warm weather, where 34 of 37 days saw above normal temperatures (May 22 – June 27) – we managed to put together a couple of very nice days.  The high temperature on the 28th and 29th stayed below 90 degrees in Okarche, and more important, dew point temperature fell to as low as 50 degrees.

Light winds, dry air and mild temperatures made for a couple of incredible evenings.  We added some of the seasons first fireworks to the mix at the BBQ on the 28th:

The heat took its toll on the peas, beans and herbs, but otherwise the garden has been producing nicely:

Elsewhere… I don’t usually post up work by others here, but Skip Talbot posted up some time lapse video of a Minnesota tornado event (June 17, 2010) that was amazing!  The video is over six minutes long, but well worth the time to check out: http://www.youtube.com/watch?v=raoJU-OevN0&feature=player_embedded

Finally… the first Hurricane of the Atlantic 2010 season is Alex.  With a pressure of 28.32 inches and 80 M.P.H. winds… the eye is now evident this morning about 187 Nautical Miles southeast of the Brownsville, Texas radar site:

Heat and Thunder… likely and possible…

Let the fun begin.  June 22nd marks the first day that the record high temperature in Okarche is 100 degrees or higher – for 78 straight days.  It only makes sense that we are pushing 100 degrees on the 23rd.

There is also a slight risk of severe thunderstorms this evening as a front has pushed into the northwest part of the state.  While little in the way of upward forcing exists – other than frontal convergence and surface heating… this should still be sufficient for the development of isolated storms.

Any storms that do form will likely produce marginally severe hail and strong gusty winds.  There will also be the potential for heat bursts when the storms rapidly weaken late this evening.

Once considered rare… the occurrence of heat bursts seem to be more common than once thought.  A heat burst is characterized by strong winds and a rapid increase in temperature and decrease in dew point.  It is theorized that a heat burst is caused when rain evaporates into a parcel of dry air high in the atmosphere making the air denser than its surroundings.  The parcel descends rapidly, warming due to compression, overshoots its equilibrium level and reaches the surface.

One of the most important aspects of getting a heat burst is getting a thunderstorm to form in the first place.  If storms do form this evening… heat bursts will be possible.  Time will tell…

- NO SEVERE WEATHER EXPECTED -

Well, I’ve decided to bring the daily Severecast to a halt… simply because there doesn’t look to be a significant severe threat for the remainder of the month.  That’s stretching things out a bit, but there have been no signals of the storm track returning to the state in the near future.  Severe weather looks to be making a regular appearance in the central and northern plains, and there will no doubt be an isolated thunderstorm capable of a severe event or two in Oklahoma (primarily the panhandle and far west) – but until a substantial threat shows itself, we may as well put the project to rest.

What may be an appropriate way to wind down the Oklahoma portion of the severe weather season is a nice sunset.  For anyone around here that didn’t get to see tonight’s… it was incredible!

SEVERECAST DAY 111 – 7:00 a.m., SATURDAY, JUNE 19

…NO ORGANIZED SEVERE THUNDERSTORMS FORECAST…

AN UPPER LEVEL HIGH PRESSURE AREA WILL REMAIN SOUTHEAST OF OKLAHOMA THROUGH THE PERIOD… WITH STRONGER SOUTHWESTERLY FLOW TO THE NORTHWEST.

THE ATMOSPHERE ACROSS THE STATE WILL BE WARM.. MOIST AND UNSTABLE TODAY BUT WITH LITTLE IN THE WAY OF ANY FEATURES TO FOCUS LIFT.  THE EXCEPTION WILL ONCE AGAIN BE THE PANHANDLE WHERE A DRY LINE WILL BE FOUND THIS AFTERNOON.

A FEW ISOLATED THUNDERSTORMS ARE POSSIBLE FROM WESTERN KANSAS INTO WESTERN TEXAS WHERE LOCALIZED AREAS OF CONVERGENCE AND INTENSE HEATING CAN OVERCOME THE STRONG CAPPING WHICH IS IN PLACE.

ANY STORMS THAT DO FORM WILL HAVE THE POTENTIAL TO PRODUCE HAIL AND DAMAGING WINDS.  THE CHANCE FOR ANY ONE SPOT ALONG THE LONG DRY LINE TO EXPERIENCE THUNDERSTORMS IS QUITE SMALL.

ON THIS DATE IN 1953… TWO WEAK TORNADOES FORMED IN WOODS COUNTY AROUND LUNCH TIME.  THE DINNER TIME TORNADOES WOULD TAKE PLACE IN SOUTHWEST OKLAHOMA IN STEPHENS AND GRADY COUNTIES WHERE ONE PERSON WAS INJURED.

SEVERECAST DAY 110 – 7:00 a.m., FRIDAY, JUNE 18

…NO ORGANIZED SEVERE THUNDERSTORMS EXPECTED…

AN UPPER LEVEL HIGH PRESSURE AREA OVER SOUTHEAST TEXAS WILL BUILD TOWARD OKLAHOMA WHILE THE MAIN STORM TRACK REMAINS WELL TO OUR NORTH AND NORTHWEST.

AS WAS THE CASE YESTERDAY…A DRY LINE WILL BE FOUND THIS AFTERNOON NEAR THE WESTERN END OF THE OKLAHOMA PANHANDLE.  CONVERGENCE AND STRONG HEATING THIS AFTERNOON WILL CAUSE ISOLATED THUNDERSTORMS TO FORM FROM KANSAS SOUTHWARD TO THE TEXAS PANHANDLE.  SUSTAINED, VIGOROUS UPDRAFTS WILL BE CAPABLE OF PRODUCING GUSTY WINDS AND SMALL HAIL.  HOWEVER… OVERALL THREAT IS TOO SMALL TO OUTLINE.

ON THIS DATE IN 1973…”IT COULD HAVE BEEN MUCH WORSE.”  SEVERE THUNDERSTORMS STARTING PRODUCING TORNADOES JUST AFTER 4:30 P.M. FROM THE NORTHEAST TO THE SOUTHWEST CORNER OF THE STATE.  A LARGE F3 TORNADO MOVED THROUGH FREDERICK IN TILLMAN COUNTY.  THE TORNADO PASSED JUST SOUTH OF THE TOWN CENTER.  LOSSES TOTALED THREE MILLION DOLLARS AS 13 HOMES WERE DESTROYED AND 63 WERE DAMAGED.  MANY BUSINESSES WERE TORN APART, AND MOST OF THE 58 INJURED WERE AT A NURSING HOME.  LUCKILY, NOBODY WAS KILLED.
