Weather Xtreme: Strong Storms Possible on Sunday, Heat Cranks Up for the Workweek

| July 11, 2020 @ 4:30 am

The Central Alabama Weekend

We’ll have a northwesterly flow across Central Alabama on Saturday which will allow the humidity levels to drop slightly due to drier continental air. We’ll have plenty of sunshine across the area and no measurable rain is expected throughout the day. Afternoon highs will max out in the lower to mid-90s, but the index values will stay below advisory criteria.

Nearly all of Central Alabama is under a level 1 Marginal Risk for severe storms on Sunday as that helpful northwest flow will send a shortwave trough in our direction. Moisture-rich and unstable air will be brought into the area by a southwesterly flow at the lower levels, providing the ingredients for thunderstorm development especially during the afternoon and evening hours. The main threats from the stronger to possibly severe storms will be from damaging wind gusts up to 60 MPH. Timing looks to be from 12:00 pm to 9:00 pm. Not everyone will see rain as they will be scattered in nature and rain chances will only be 40-60% from northwest to southeast. Highs will be in the lower to mid-90s.

The Work Week Ahead

The trough will get hung up south of the area that will allow for the potential for scattered showers and storms for the southern parts of Central Alabama on Monday, but the northern two-thirds of the area will remain dry throughout the day. Highs will be in the lower 90s across the area.

Nearly the same story on Tuesday as the southern parts of the area will remain in a little more unstable air, but rain chances will be slim at best. The rest of Central Alabama will remain dry and hot. Highs will reach the lower to mid-90s.

Wednesday and Thursday will be even hotter as a ridge will build into the area from the Southern Plains. There will be just enough deep moisture that an isolated shower or two will be possible during the afternoon hours, but nearly everyone will stay dry on both days. Temperatures and humidity levels may be high enough that head advisories may be needed. Highs on both days will be in the mid to upper 90s.

Just a little more moisture is allowed to move into Central Alabama on Friday that will help bring the temperatures down by a couple of degrees and will give us a small increase in the scattered afternoon shower and storm chance. Highs will be in the lower to mid-90s.

The Tropics

At 11:00 pm on Friday night, Tropical Storm Fay was continuing her northward trek across New Jersey while weakening. Winds were at 40 MPH and the minimum central pressure has risen to 1001 MB. Fay is expected to either weaken into a depression or become post-tropical at some point on Saturday morning. Other than some gusty winds and a few minor flooding issues in poor drainage areas, no major impacts are expected across New England. The rest of the Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico remains rather quiet.
