Outlook (Thursday-Sunday)

…Slightly cooler with chances of precipitation into the weekend…

A strong cold front moved eastward across the Siouxland and Great Lakes over the past 24 hours.  The weather map this Wednesday evening shows the front extending from southern Indiana to northeast Oklahoma.  The front then meanders southwestward across the state to the Texas South Plains.  At 11 pm, the front was nearly on top of Okarche.  The front has slowed and is not very sharp across the Southern Plains.  While a few degrees cooler, dew point temperatures are still in the 70′s to the north of the front in Oklahoma.  There have been a few showers and thunderstorms across western and northern Oklahoma this afternoon and evening.  Model data suggests that storms will be possible into Monday morning, and may increase in coverage across northwest Oklahoma.

Strong mid level flow extends from British Columbia east southeastward across the Great Lakes and Ohio Valley.  This belt of strong wind will persist into the weekend as a trough maintains its position over the eastern part of the country.  Meanwhile, high pressure that has been located over the Southern Plains will move steadily westward and weaken some over the next 72 hours.  The end result will be slightly cooler weather, and areas of showers and thunderstorms through at least Saturday.

…Hazards…

Heat index temperatures will reach or exceed 105 degrees across south central and southeast Oklahoma on Thursday.
