11/21 – The Chief’s “Warming Trend” Monday Morning Forecast

A weak disturbance currently over northern Texas will track east today and tonight, passing through the lower Mississippi Valley. Showers have developed well ahead of that system over western and central Louisiana. Increasing clouds can be expected this morning along with a few showers this afternoon/evening. Temps are well above freezing to keep precip liquid. Rainfall totals should be fairly minimal due to fairly dry low/mid-levels.

The disturbance will move quickly east of the region on Tuesday with zonal flow developing. Showers may still be lingering in coastal waters but likely just on the southern periphery of the area marine zones with a steady southward shift as the day progresses. Temps start to moderate some during the day, but won’t be appreciably noticeable until Wednesday when highs top out around 70 degrees.

Beyond this point of the forecast, uncertainty increases considerably. Models suggest that a deep disturbance will dive south out of Canada and will swing through the entire Mississippi Valley on Thanksgiving and shift eastward. This setup would yield scattered to numerous showers and drop temps for a couple days as a cold front rolls through.
