10/13 – The Chief’s “Morning Cold Frontal Passage” Thursday Morning Forecast
Cold frontal passage will occur this morning with a 30% chance of showers and thunderstorms associated with it. Mostly cloudy skies will clear this afternoon to plenty of sunshine. Temperatures will reach the mid-80s with drier air arriving this afternoon and evening. Expect clear and cool conditions overnight with temperatures cooling to the 50s.
A northerly wind component will continue tonight but will shift to the east by midday Friday. High pressure to the northwest will steadily move to its southeast. The area of high pressure will be centered over the Florida Panhandle Saturday increasing the moisture in our area. Clear skies will continue through Saturday, with Sunday being a day of transition.
Clouds and humidity will return Sunday, and another cold front will move in early next week. An upper-level disturbance coming from the Pacific Northwest will drag a trailing cold front early next week. At this time, the slope of the front looks fairly shallow and should only support rainfall. However, a few thunderstorms cannot be ruled out. The timing of this boundary moving through is rather uncertain at this time, with frontal passage anytime late Monday through sunrise Tuesday. A much colder airmass will take hold for the region, bringing well-below seasonal temperatures and breezy conditions. Overnight lows will drop to the mid and upper 40s post frontal passage, with daytime highs in the upper 60s to low 70s.
