Rainfall – January 5-6, 2016 (Closed)

Light rain moved across the area on January 5th and 6th.  Radar rainfall estimates showed three bands of slightly heavier precipitation amounts with the highest estimates over northern Logan County.

A big welcome goes out to new station OK-PY-17 (2.5 MILES SOUTHWEST OF PERKINS IN PAYNE COUNTY).  This station helps fill a big hole over the southwest part of Payne County, and we look forward to future observations.

There continues to be a lot of sleet/ice melt contamination with observations from automated rain gauges.  I have left Mesonet and Weather Underground observations out of this summary.

Rain amounts from the morning of January 6th – will be updated after January 7th reports are received:

Light rainfall

A few light rain reports from CoCoRaHS observers:

0.01 – 12/24/15 – Fay 2.4 NE (OK-BL-2)

0.01 – 12/24/15 – Enid 3.6 WNW (OK-GD-7)

0.02 – 12/20/15 – Yukon 3.3 S (OK-CN-25)

0.05 – 12/18/15 – Enid 3.3 W (OK-GD-9)




Post ice storm

A couple of images from Okarche.  Yes, another impressive ice storm landed in our laps and we have some extensive tree and power line damage across much of the area.  It appears that all of the six county area saw heavy ice accumulations, with the exception of central and eastern Payne County.  Power in some places may be out for upward of a week or better.

The largest outages from the OG&E system watch page at 9 am on November 30th:

El Reno: 4,872 customers

Enid: 4,343 customers

Yukon: 2,846 customers

Guthrie: 1,518 customers

Piedmont: 1,058 customers



Rainfall – November 26-30, 2015 (Closed – finally)

I’m including a radar rainfall estimate graphic, but it’s really pretty much worthless.  Estimates by radar performed horribly compared to ground truth measurements.  The high estimates over northwest Canadian County are a result of contamination from wind farms.

This long duration precipitation event produced significant / in some cases record setting / rain, sleet and freezing rain across the entire area.

No attempt was made to quality check the following observations.  Low totals may be a result of incomplete observations.  Most non-CoCoRaHS observing sites use automated rain gauges which do not handle freezing/frozen precipitation well.  In addition, precipitation on a specific day may not be the day that the precipitation fell, but rather melted.
