Heat, strong storms, and heavy rain ahead

A strong surge of cool Canadian air will push into the eastern U.S. by mid-week, dislodging the current hot and sticky airmass over Fredericksburg. But this pattern change will mean strong to severe storms today and tomorrow with the likelihood of some associated heavy rainfall. This graphic from the Weather Prediction Center shows the potential precipitation amounts through Wednesday morning:Day 1_2 qpfThe purple shade bisecting the Fredericksburg region represents 1.5 inches, which could alleviate recent dryness if it doesn’t come down and run off too quickly. Unfortunately that’s likely what will happen so we may be faced with flash flooding issues.

Today’s high temperature will once again top out in the mid-90s with plenty of humidity. The more sunshine that occurs the greater the atmospheric instability will be, bringing stronger storms. The worst of the storms will likely hold off until dinnertime with some scattered activity occurring this afternoon. The main threat for the ‘Burg during today’s severe weather is a risk of severe winds (>58 mph) during thunderstorms. Of course heavy rains and lightning will also demand attention to the weather as well.

Tomorrow – Tuesday – the cold front at the leading edge of the Canadian air will be closer and the convection will begin earlier in the afternoon. Thus temperatures won’t quite make it into the 90s, maxing out instead in the upper 80s before the storms hit. High winds, heavy rains, and lightning will once again be the primary threats.

Then starting Wednesday…..ahhhhhh!! The weather will be unbelievably nice for July. But more on that later. Meanwhile please be weather alert today and tomorrow, staying tuned to media updates as conditions in and around Fredericksburg could change rapidly. We have to pay the piper before we get the nice weather.
