A highly amplified jet stream pattern with a trough to the east and a ridge to the west has allowed cold Canadian air to drop into the region. This trough/ridge combo has put our area in Northwest Flow, a cool, dry flow that typically brings colder air in the winter and pleasant humidity and mild temps in the Spring.
Lows this morning fell into the 30s across many areas north of I-10, with even some areas south of I-10 seeing cold temperatures. It was 37° before 7am on Tuesday 4/24 making it the coldest morning on that date in Mobile in over 125 years. The old record was smashed by 6 degrees! Other areas seeing record lows were Jackson AL, Pensacola and Crestview FL. Pensacola fell to 45° which tied the old record.
It becomes more summmer-like as the days progress this week. The trough of low pressure over the eastern US will lift out and the ridge out west will build in bringing warmer air back to the region. We'll see 80s by Wednesday with mid 80s by the weekend. Higher humidity will return to the area as storm chances creep back in by early next week.
