Friday Morning Update

Alan Crone's Weather Blog: Chance For Rain On Sunday

Posted: Updated:
The nice and mild weather pattern will continue for the next several days with increasing temperatures for both overnight lows and daytime highs.   Readings this afternoon should move into the lower 50s with sunshine and southwest winds around 10 to 15 mph.   A disturbance in the southern stream will move across Texas this weekend with some showers and storms across the Lone Star state.   This system may slide northeast and brush portions of eastern and southeastern OK Sunday.   We'll add a slight chance of showers Sunday and lower the highs due to the increase in cloud cover.

The ice and snow cover across most of Oklahoma was no match for the increasing sun of angle of early March.   Temperatures yesterday afternoon beat our projections as the snow-ice cover quickly eroded and had little impact on surface readings, other than extreme eastern OK and western Arkansas.  Temperatures this morning will remain below freezing.   

The split-flow pattern remains for the next several days.   The northern (polar) jet is well to our north.   The southern stream will send a disturbance out of the southwestern U.S. across Texas Saturday and Sunday providing a chance for showers and storms near and south of the wave.   Model data has continued to trend this system slightly northward with each run with the disturbance and this means an increase in moisture across eastern OK.   We'll be adding a chance for showers Sunday and will bring the highs down a few degrees. 

Later next week, we see signs of another upper trough developing out of northwestern Canada moving southeast.   Another surge of colder air will likely move southward late next week, but the southern reach of this air-mass will remain a mystery at this point.  It looks like this may not occur, however, until possibly next weekend.   The pattern late next week into the weekend should also support some increasing precipitation chances as a system attempts to develop across the south Texas area and moves northward.  

Temperatures today will move into the lower to mid-50s with sunshine and southwest winds.   Saturday morning starts in the upper 20s and ends around 60 with sunshine and south winds.   Sunday morning lows will be warmer, into the mid-30s, but highs will drop down into the 50s due to increasing clouds with south winds around 10 mph.  We'll include a slight chance of showers across the area Sunday, mainly eastern and southeastern sections of the area.   Monday into Wednesday will support a nice warming trend.   Lows will move into the 30s and 40s with daytime highs in the mid-60s Monday, the upper 60s Tuesday, and the lower 70s Wednesday.   

   Enjoy the weekend.
