Weather Blog: Rain to Linger Through Friday


Afternoon water vapor imagery shows upper low making good progress to the east across North Central Texas. At the surface, a cold front extended across Northeast Oklahoma, with gusty north winds and falling temperatures behind the front. Temperatures this afternoon have dropped 10 to 15 degrees, from the mid 50s earlier to lower 40s now across Northeast Oklahoma. Ahead of the front, temperatures were still in the mid to upper 50s across Western Arkansas and Southeast Oklahoma.

We have generally had rainfall totals around a half inch this afternoon, but Tulsa and surrounding areas have received over 2 inches of rain over the last few hours. Another 1 to 2 inches is possible
through Friday, mainly south and east of Tulsa.

Winds have been strong, but below advisory criteria so far, with the exception of some areas in Osage/Pawnee counties. Pressure rises behind the front have really dropped off since this morning, and this is confirmed by the rather slow movement of the cold front this afternoon. We will leave advisory as is for tonight, as there will be a strong pressure gradient through early Friday morning.

We had a few thunderstorms as far north as Tulsa this morning into early afternoon, but lightning has dropped off a bit north of Interstate 40 over the last hour or two. The most active area for convection has been just north and east of the upper low, near Sherman. With the upper trough still west of the area, we will maintain low thunder chances this evening across portions of Eastern Oklahoma and Western Arkansas given some elevated instability still present.

Rain will linger especially across Western Arkansas and Southeast Oklahoma through Friday, but the weekend looks dry and warmer as upper ridge builds across the area. Temperatures actually look just above normal through the next several days, ranging from the mid to upper 50s for highs and 30s for highs.
