BREAK FROM THE HEAT
We hit 97 at Camp Mabry and 98 at ABIA, making today the hottest day of the year so far! A break from the heat is on the way by the end of the holiday weekend with a passing cold front. High temperatures will hold on to the 90s Sunday then “cool” closer to our seasonal temperatures in the middle 80s for Memorial Day and the beginning of next week.
POSSIBLE SEVERE STORMS
Isolated storms will be possible Sunday afternoon then become much more widespread into the overnight. Storms could possibly become strong or severe with the highest threats large hail and damaging winds. These storms will subside after sunrise on Memorial Day before another round later in the afternoon. Storms will be the trend through next week, possibly bringing us some high rainfall accumulation totals. While all forecast models do keep isolated storms in the forecast, there is a big difference between rainfall accumulation from model to model by the end of this week. Models are in pretty good agreement for 1”-2” Sunday night, but then models begin to go in different directions. The European model is by far the wettest with up to 6” possible by next Friday night. The GFS, however, is much less active with only 1.5” accumulating.
At this point, as long as the rain falls over the course of multiple days as opposed to all at once, we should be able to handle it without significant flood threat. We’ll have to keep a close eye on the atmosphere as we go through the week to get a better idea of what we can expect. Stay tuned!
