12/8 – Rob Knight’s WINTRY MORNING Forecast

A similar scenario from the previous forecast. Circulation around an upper level low over Hudson Bay and the associated surface front extends to deep south TX. Moist SW flow continues to bring our third day of overrunning precipitation. A stretched out low was located in the Gulf of Mexico along an old frontal boundary will continue to push east into FL. This kink in the flow will be the best chance to see winter precipitation. Radar shows this impulse in southwest LA and it will push east- north east this morning. Some bright banding evident of high winter precipitation rates are moving in NW PR County. I’m still concern for sleet and snow on the back edge of the precipitation as we see melting. The best chance for sleet and snow will enter our forecast area from the west closer to sunrise then return to liquid heading towards mid-morning/midday.

This current trough will be the kicker to finally clear things out for the weekend. In the wake will be very cold temperatures with the lowest values Saturday morning. Mid to upper 20s forecast at most locations with the exception of lower 30s near tidal lakes and the Gulf. Several impulses continue next week around the Canadian low pressure system, however dry conditions will prevail next week with another surge of cold air Tuesday lasting the remainder of the week.
