Alan Crone's Weather Blog: Cold With Chance Of Wintry Mix This Week

We’re tracking several short waves embedded in the flow that will bring precipitation chances to the state for the next few days.   The first one arrives Tuesday night into Wednesday and the second Thursday night into Friday and the third late this weekend.    Temperatures today will remain chilly with high in the lower 40s.    The temperatures this week should remain on the chilly side before seeing some minor improvement by the end of the week.

A weak boundary moved across the area early Sunday and a surface ridge of high pressure located across the central plains will keep the highs today in the upper 30s and lower 40s along with north winds and mostly sunny conditions but some clouds will be likely at times.   Readings across the southeastern portion of the state will be slightly warmer with highs in the mid-40s.   The first short wave will round the base of the western U.S. trough and eject into the region Tuesday night and Wednesday morning.   Data suggest a return of southerly winds Tuesday into Wednesday helping to bring some moisture back across the area.   Temperatures may still be cold enough to support some light wintry precip, either sleet or snow, early Wednesday morning for a small window of time, before the profile warms to support mainly rain.   Any amounts would be relatively light.   We’ll not know the exact timing and possible impact for another day.   At this point, it appears this wave will be minor.

The second wave appears Thursday night into Friday with temperature profiles in the atmosphere supporting all rain Thursday across eastern OK, and the third Saturday night into Sunday.   The third wave takes more of a southerly route and would bring higher chances for rain to southeastern OK and northeastern TX Saturday night.   The air profile on the departing side of the upper trough would be cold enough to change the rain to snow Saturday night across far southeastern OK.   This will need to be watched closely in the data for the next few days as colder air should surge across the state Saturday and the exact trajectory of the wave will have plenty of time to change it’s course in the data.   Regardless, the air-mass this weekend looks cold with lows in the 20s and highs in the upper 30s and lower 40s.

Thanks for reading the Monday morning weather discussion and blog.

Have a super great day!
