Expect a windy and warm Monday with highs in the upper 80s near 90.  South winds from 15 to 25 mph will be common with mostly sunny conditions.  A storm system is approaching the area and chances for storms will begin to increase soon.

 I hope you had a great weekend, and also a super Mother's day.

 The next two days will be closely related regarding weather conditions:  humid, warm, and windy.

The next major system will be approaching the area Wednesday with a chance of strong to severe storms.  The timing on the system will be tweaked as the data continues to arrive, but the current timing will be for the Wednesday afternoon periods extending into pre-dawn Thursday.

 Before we get closer to the main upper level trough currently to out west, the upper air flow will bring a disturbance into south-central OK late tonight and also Tuesday afternoon.  The Tuesday afternoon wave will have a chance to initiate a decent coverage of storms Tuesday evening to our southwest.  Some of these Tuesday night storms may survive and move into the southeastern OK coverage area Wednesday morning. 

 

The short term surface feature includes a dry line across western Ok that will move eastward later today, but will remain west of the I-35 corridor.  Areas west of the dry line will reside in extremely dry and hot air. Yesterday an all time record high for the state was set for May 8th with 108 degrees reached in Altus.  A number of locations across western OK hit the century mark and more 100 degree readings are likely today across the far western part of the state as afternoon humidity values plummet to single digits.  The fire danger remains very high across the western third of the state. 

The main upper level trough will move east and northeast of the state Wednesday night and early Thursday, but should begin to "close off" and become almost "cut off" from the upper air flow this weekend. This will place the state in the northwest flow aloft regime, which means a few showers or storms can't be ruled out.  I don't see very strong signals at this point for the weekend, but will keep a 20% pop for Saturday to advertise the potential that may exist.
