FIRST ALERT: Very hot, humid, and hazy on Sunday, with fewer afternoon storms

First Alert Weather 9p 6-27-20

BIRMINGHAM, Ala. (WBRC) - THE OVERNIGHT: It turned out to be a very active evening with numerous tornado warnings over Cullman County. Thermal boundaries in the area caused storms to rotate resulting in a few brief tornadoes. That threat has ended and thankfully the weather will be much calmer overnight. The sky will be partly cloudy, with patchy fog, and lows near 72º. 

FEWER STORMS FOR SUNDAY AND MONDAY: An upper level ridge will help limit the number of storms over the next couple of days. That said, the chance for storms will be non-zero on Sunday and Monday. The greatest chance for Sunday will be over northeast locations, and for areas south of I-20. Elsewhere, plan on very hot days, with a hazy sky overhead. Highs will reach the low 90s, with the heat index nearing the triple digit mark in a few locations. The chance for a pop-up storm in the afternoon will be near 30% for the next two days.

FIRST ALERT FOR MORE STORMS STARTING ON TUESDAY: The high pressure ridge helping to limit rain chances over the next two days looks to flatten by the middle of the week, with a stormy pattern returning to the area. This will bring multiple of rounds of storms, including the possibility of organized complexes of storms, capable of producing strong winds, frequent cloud-to-ground lightning, hail, and heavy rainfall. We will have breaks each day, in-between rain events, but I would plan for the possibility of storm delays for Tuesday, Wednesday, Thursday, and Friday. We will know more specifics about timing once we get closer to the middle of the week and have the higher resolution data. It’s possible some of this wet weather could arrive early in the day but I would still try to get an early start with respect to planning. The afternoons and evenings will continue to be very favorable time periods for storms. The pattern won’t change much by the end of the week, so rain chances will likely remain elevated through next weekend.

The dust causing the hazy conditions looks to move out on Monday, so air quality levels will improve early next week; however, another large plume of dust could return later in the week. I’ll be sure to share the air quality outlook and I will show you when to expect the highest rain chances next week in my forecast starting at 9PM on WBRC Fox6.
