Alan Crone's Weather Blog: Wet And Cool Tuesday

A strong storm system will be influencing the state today and tonight before rapidly exiting eastern OK pre-dawn Wednesday.    Cool temperatures will remain Wednesday and Thursday with a noticeable warming trend likely Friday through most of the weekend.   Today will be windy, cold, wet, and raw for parts of eastern OK.   Some locations north or northwest of the Tulsa metro will have lower rain chances compared to the south.   The best chances will remain along and south-east of the I-44 corridor region, including southeastern and east-central OK.   Temperatures today will remain in the 40s along with gusty north winds from 15 to 35 mph.   A wind advisory may be required later today for parts of south central or southeastern OK.    A quick change-over from rain to wet snow is a possibility but mainly for northwestern Arkansas and a very small area of southeastern OK.

The surface low developed yesterday afternoon in response to the approaching upper level system across the Rockies.  This low is now located across south-central TX and will quickly move east and northeast today and tonight.   The low will be positioned across northern Louisiana this afternoon and should be located across central Tennessee Wednesday morning.   The weather geeks in the crowd will notice this low deepening to nearly 988mb by Wednesday morning.   A significant severe weather outbreak is likely this afternoon and tonight across part of Louisiana, Mississippi, Alabama and a small area of Florida.  

Rain has developed this morning across the southwestern and south central OK region and is advancing northeast.   The hi resolution runs (models) are suggesting a stout gradient from rain to no rain across part of northern OK this morning.   I’ll keep the metro around 70% and locations south at 100%.    

As the powerful upper level low moves over the state this afternoon and tonight, colder air aloft will attempt to move down to the surface.   This is when some rain may change to snow across northern Arkansas.   Most data (and past experience) would suggest this possibility would occur around LeFlore County in Oklahoma to locations across northwestern and north-central Arkansas.   No accumulation would be expected around far southeastern OK but some 1 inch snowfall is possible across part of northern Arkansas Wednesday as the system is leaving the area.

Wednesday morning we’ll be experiencing very strong northwest winds at 25 to 35 mph for a few hours before the winds decrease speeds to near 15 and 20 mph by the afternoon.   The morning clouds will quickly erode as even drier air moves across the area.  

Thursday a surface ridge of high pressure will be nearby allowing for pleasant and cool weather into Friday. 

The weekend should feature increasing south winds and increasing temperatures.    Highs this weekend will be near 70 before another cold front arrives sometime Sunday night into Monday.

Thanks for reading the Tuesday morning weather discussion and blog.

Have a super great day.
