10/23 – Rob’s “Colder Air” Workweek Forecast
A much quieter morning this morning with the cold front that triggered yesterday`s weather currently along a Birmingham to Pensacola line, with an area of low pressure near Memphis at this time. Some low clouds wrapping around upper low are noted on satellite over Mississippi, but most of the area is clear.
Upper pattern is in the process of digging a deep trough into the eastern third of the country. We should see abundant sunshine across the area today with cooler temperatures than earlier in the weekend. High temperatures today will be in the 70s, even with full sunshine. Overnight lows will range from upper 40s to mid 50s. A stronger shortwave will sweep through the area on Tuesday, reinforcing the push of colder and drier air. Little in the way of clouds or precipitation expected with the frontal passage. High temps on Tuesday likely to be a few degrees cooler than today, but with the frontal passage, late afternoon and early evening temperatures could drop pretty quickly. Overnight lows Tuesday night will be the coolest that we`ve seen since mid-March in many areas, with lows near 40 expected across the northern half of the area. Temperatures will only recover into the upper 60s on Wednesday. 35
High pressure will build across the area on Thursday, but will be very short-lived as the upper trough over the Great Lakes reloads. This will bring a cold front for the weekend with warming temps and increasing humidity Friday. The front should bring minimal activity along with most of the energy moving through the viewing area Overnight Friday and through the day Saturday.)
