1/27 – The Chief’s “Approaching Cold Front” Friday-Eve Morning Forecast
A weak cold front diving southward through the mid-west and lower Tennessee valley will move across the area during the day on Friday, with the upper flow returning northwesterly into the weekend. There isn’t sufficient moisture so I’m not expecting any weather with passage with the exception of a few outer coastal showers early Friday morning. Cold high pressure moves back into the area Friday night and Saturday.
Sunday and Sunday night will be the quieter period in the long term forecast. Deep layer northwest flow will remain in place, and this will keep a dry and very stable airmass over the Gulf South. As a result, mostly clear skies and a fairly large diurnal range can be expected. Highs on Sunday will be near average in the lower to middle 60s, but the dry airmass will allow for strong radiational cooling Sunday night. Lows should drop a good 25 to 30 degrees down into the upper 30s and lower 40s.
Monday will be a period of transition as the northwest flow pattern gives way to a disturbance moving SE. In the low levels, southerly flow will be on the increase, and some moisture advection is expected. This moisture should allow for some marine layer low cloud to occur by the afternoon. A fast moving and vigorous system will slide from Texas through the Lower Mississippi Valley from Monday night through Tuesday. A very progressive pattern will persist through the middle of next week.
