Conditions Around Central Alabama At The Midday Hour

| May 11, 2017 @ 12:11 pm

At the midday hour across Central Alabama, ridging in place over the southeast is keeping any rain out of our area. A few showers have moved through the extreme northern parts of the state earlier today, and a few are out there at this point as well, especially over parts of Lauderdale County near Zip City. For Central Alabama, we’re high and dry with a mix of sun and clouds at this point.

Temperatures across Central Alabama at 11:27AM are running in the upper 70s to the lower 80s. A few locations are currently tied for the warmest at 81 degrees, to go along with a few locations tied for the coolest at 77 degrees.

AIR QUALITY CHECK
The Air Quality Index for the Birmingham Metropolitan area will be in a CODE YELLOW (MODERATE) at 71 due to increased levels of Ozone and Particulate Matter (PM2.5). Unusually sensitive people should consider reducing prolonged or heavy exertion outdoors.

REMAINDER OF THURSDAY’S WEATHER
Throughout the remainder of the daytime hours, clouds will be on the increase but we should stay dry. Afternoon highs will top out in the upper 80s to the lower 90s across Central Alabama from north to south. Later this evening, there will be a small risk for a few showers moving across the western parts of the area, especially after 8PM. Those showers will spread out over the northern parts of Central Alabama for the overnight hours, sometime before midnight according to the latest HRRR, but will quickly move to the northeast of of the area within a couple of hours. Overnight lows will be in the lower to mid 60s.

A FEW STRONG STORMS POSSIBLE ON FRIDAY
The morning will start off with some showers moving mainly over the northwestern parts of the area before dawn, then some heavier showers and storms will develop and move across the northern half of the area during the morning through the early afternoon hours. Surface based instability levels will be lower during this time, and storm relative helicity will be low as well. A few strong storms could be possible at this time, with gusty winds as the main threat.

The larger threat for strong to marginally severe storms will come later during the late afternoon through the midnight hour across Central Alabama, as more storms will have developed due to the heating of the day, and with the surface-based instability values being much higher, topping out in the 2,700-3,400 J/kg range. The overall risk will remain marginal for severe storms with gusty winds and some small hail as the main threats. The low-level flow and storm-relative helicity values look to be too low for any tornadoes.

So the bottom line for the day, skies will be cloudy throughout the entire day, with showers and thunderstorms likely. Strong to marginally severe storms will be possible during the afternoon and early evening hours, with gusty winds and small hail as the main threats. Afternoon highs will be in the mid 70s to the mid 80s. Rainfall amounts of 1/2 inch are likely, with some isolated higher totals possible. Rain and storms will continue in the evening and overnight hours, but will be out of the area by early Saturday morning. Overnight lows will be in the upper 50s to the mid 60s.
