11/21 — Brantly’s “Showers Saturday” Thursday Evening Forecast
Increasing cloudiness will continue to be the trend through the night and into Friday. Because of the cloud cover, some heat will get trapped in the lower levels of the atmosphere and lows should only dip into the upper 50s and lower 60s.
Winds coming out of the south will bring some moisture off the Gulf during the day tomorrow, and expect to see thicker cloud cover and increased rain chances develop by tomorrow night. Temperatures will remain very mild with highs in the middle 70s expected.
A strengthening low pressure system moving across the Midwest will produce a decent cold front by tomorrow afternoon across the southern states. This front will sweep through the South Mississippi area late Friday night into Saturday morning. At this time, the risk of thunderstorm activity looks very. As a result, only have showers are in the forecast for the Friday night and Saturday morning timeframe.
The front should sweep through the area by mid-day Saturday, and high temperatures should occur in the morning hours across the area. Cooler and drier air should begin to quickly move into the area by Saturday afternoon, leaving us with a dry forecast in place by the evening hours. Temperatures should fall from the upper 60s and lower 70s Saturday morning into the upper 50s and lower 60s by the evening hours. By late Saturday night, temperatures should drop into the 40s as winds from the northwest bring in cooler air.
Sunday, expect to see highs only climb into the lower to middle 60s. Lows on Sunday night will be the coldest of the forecast period as clear skies and light winds allow for some very quick cooling. Temperatures should dip into the lower and mid 40s. Winds will switch to the south again by Monday, and increasing flow off the Gulf will allow for some modification in temperatures. Temperatures should warm into the upper 60s by Monday afternoon.
Increasing cloud cover and scattered rain showers should develop through the day on Tuesday. A few thunderstorms may develop Tuesday afternoon and evening. At this time, models are not showing signs of any strong or severe thunderstorm development. Temperatures should warm back into the middle 70s by Tuesday due to the strong onshore flow pattern in place across the area.
Slightly cooler air should move into the area, and highs should be a few degrees cooler in the middle to upper 60s on Wednesday. The front should begin to lift north as a warm front Wednesday night and Thursday resulting in continued cloud cover and shower activity into Thanksgiving Day. Temperatures should also warm back into the lower 70s as the warm front surges northward through the day.
