Alan Crone's Weather Blog: Storm System Exiting The State

Good morning.   Our major storm system is nearing the end of its impact across the state but will produce some precipitation for the first part of the day before exiting across far northeastern OK later this afternoon.   While the main impact continues to be the flooding rainfall across eastern OK, some wintry precip can’t be ruled out this morning through midday as main upper level low moves over the northern OK region.   Locations near and west of the metro will have the chance of experiencing some wintry mix while the eastern and southeastern sections will see the rain ending by late morning.

Temperatures aloft with the main upper level low will allow rain to transition to some sleet near and west of the metro before briefly turning to some snow by midday to early afternoon as the wave exits the area.  Locations across the far eastern and southeastern part of the state will more than likely remain all rain but a brief transition to some wintry mix can’t be ruled out as the cold core low passes the area this morning into midday.   

Temperatures today for the metro and surrounding area should start in around 35 but will slowly drop as the cold core low approaches the area.   We’ll eventually see some freezing temperatures around noon to the early afternoon hours but the precipitation will be ending to the northeast as these readings drop into the freezing range.

Another upper level wave will eject across the northern third of the state Tuesday night into Wednesday morning before moving into the central plains.   This should bring some snow showers across far northern OK and southern Kansas for a small time period late Tuesday into Wednesday morning.   A dusting will be possible with this wave with any impacts expected to the northwest or north of the Tulsa metro. 

Temperatures will remain rather chilly for the entire week.   Today’s readings should remain in the mid 30s  for daytime highs with our strong west to northwest winds decreasing wind speeds late this afternoon and tonight.    The sky may attempt to partially clear overnight with Tuesday morning lows dropping into the mid-20s and afternoon highs in the upper 30s and lower 40s.   Increasing clouds are likely Tuesday night into Wednesday with the next upper air wave bringing a slight chance of snow showers to far northern OK and southern Kansas.   As the wave exits the area the clouds will clear Wednesday morning with lows in the 20s and highs in the lower 40s.   The cold air will remain across the state with morning lows in the lower to mid-20s Thursday through the weekend and afternoon highs in the upper 30s Thursday and Friday with some moderating temperatures in the upper 30s and lower 40s into the weekend.     The New Year’s Eve forecast appears cold but dry.
