The main upper level low located across the inter mountain region and four corners area will slowly pinwheel east and northeast over the next few days while weakening.   The upper flow will then take the leftover disturbance across the southern plains Wednesday night into Thursday.   Until this occurs, our weather will remain unsettled with periodic rain and thunderstorm episodes.   

We should be finished with this system Wednesday night or Thursday morning at the very latest.   The next system will be nearing the state by the 2nd half of the approaching weekend.   Temperatures will be mainly in the mid to upper 50s during the mornings and near 70 for the afternoon today and tomorrow.

The first batch of activity moved across the area Sunday afternoon.   The 2nd is now nearing the central and eastern portions of the area this morning with pockets of moderate to heavy rainfall.    The main hazards associated with this system will be the ponding of water on roadways and heavy downpours that may result in localized flooding issues.   

A flood watch is posted for portions of central Oklahoma with a few counties across southeastern OK included in this flood watch.   The Tulsa metro and surrounding northeastern OK region is not included.  

After this round of showers with thunder moves eastward this morning, we may get a break for most of the afternoon before additional spotty or scattered showers and storms develop later this afternoon and tonight into Tuesday morning.   We’ll keep a decent mention of activity for the metro.

Wednesday the above mentioned upper air disturbance will be caught up in the flow and begin moving southeast.   Showers and storms will develop in several locations and move east and southeast Wednesday afternoon and evening before a surface cold front sweeps across the state ending the threat of precipitation as relatively dry air moves across the region.   Surface instabilities and convective potential energy will be increasing Wednesday midday to evening with southern and south central section of the state having a chance for a few strong to severe storms

Pleasant conditions will occur Thursday and Friday before the next system arrives sometime Sunday into Monday.  Our storm chances will remain low Sunday into Monday until or unless confidence increases in the data.

Thanks for reading the Monday Morning weather discussion and blog.

Have a super great day!
