Temps are in the 60s this morning ahead of the boundary and should drop into the lower to mid-50s for the next few hours along with gusty northeast winds from 20 to 30 mph. Morning clouds will clear from the northwest to southeast as the main upper level forcing quickly exits the region. A surface ridge of high pressure will build across northern OK later tonight allowing for very cool conditions Saturday morning. Temperatures should start in the mid to upper 30s tomorrow morning along with some patchy frost in the valleys of eastern OK. Saturday afternoon looks great with sunshine and light southeast winds allowing afternoon highs to hit the lower to mid-60s.
The pattern continues to support an active southwestern upper air flow developing Sunday into next week. This flow usually brings active weather into the region during early spring, and the up-coming work-week appears to offer a few storm systems with thunderstorm chances.
Monday into Tuesday strong south winds will crank up as the next upper level disturbance draws near the region. A surface area of low pressure will develop Sunday into Monday across SE Colorado and SW Kansas. This low will eject into the central plains Tuesday while the trailing cold front moves across northern OK Tuesday afternoon and evening with storm chances. A few may be severe.
A secondary low will form Tuesday night into Wednesday to out southwest as the next in the series of waves approaches the region. This will quickly bring moisture back into the area Wednesday with additional storm chances Wednesday into Thursday. Severe weather threats will remain with these systems.
Thursday into Friday a surface high will build behind the departing surface boundary giving us a break from the storms with pleasant weather expected for the end of the week.
Thanks for reading the Friday Morning weather discussion and blog.
Have a super great day!
