Monday Update

Expect mostly cloudy conditions this morning with a few showers and storms.  Due to the thermal profile of the atmosphere this morning, some of the storm activity may produce small hail or some sleet.  Then clouds will gradually clear with highs near 50 in northern OK and the mid to upper 50s across southern sections.  Breezy north winds are expected today.

 The surface front and dry line are east of the area this morning but the upper level low has yet to totally clear its influence of the state.  A few showers and storms will continue early this morning as this upper air feature moves eastward.  A narrow line of showers and storms will be likely during the pre-dawn hour.  The upper level system is very strong and the cold air aloft may support some hail in spots.  This is not expected to be severe or to last long. 

 The clouds will be clearing during the midday time period with some sun later this afternoon along with gusty north winds at 10 to 20 mph.  Highs should be in the upper 40s and lower 50s.  If the clouds don't clear until late, the temperatures will be a few degrees cooler.  If the clouds clear before noon, we'll move a few degrees warmer. 

 The upper air flow is expected to remain zonal or west to east for most of the week.  A weak upper level system will brush the state Wednesday.  This will allow a weak surface boundary to slide southward into northern OK for a few hours before stalling and moving northward Thursday. 

 The next major system will be arriving Friday with a chance of storms Friday night and seasonably cooler air Saturday and Sunday.  Another powerful looking system may be possible early next week.

 A 4.7 magnitude earthquake occurred near Little Rock, Arkansas last night around 11pm.  We have received a few emails of residents in Tulsa experiencing this shake.
