5/6 – Night Rob’s “Mother’s Day Looking Good” Friday Evening Forecast
A northwest to west flow has developed in the wake of this morning’s thunderstorms, setting up a very pleasant, cooler and drier Friday night. The drier air will also allow warmer temperatures over the Mother’s Day weekend, with highs in the upper 80s for most, but nights will not be as warm and muggy as they were this past week.
By Monday, high pressure will be building back into the eastern gulf, prompting a return of southerly flow, so humidity will bump up a notch as temperatures remain above normal. The high will build closer to the region mid-week, resulting in even warmer temperatures.
Expect these mid-week temperatures to be in the low to mid 90s inland, and close to 90 along the coast. Heat index values are forecast to be in the low 100s at times across the hotter spots. Yes, it is the south, but given that it is early May, many people are not quite acclimated to the summer temperatures just yet. So, people will need to take extra precautions to stay hydrated and wear loose fitting clothing, especially if they will be spending time outside. An interesting thing occurs with the current low sitting over Missouri this morning. This low slowly moves over the of the gulf stream (warmer tropical waters) western Atlantic and stalls. It will have to be watched for tropical development. Although the season officially starts June 1, named systems are not that uncommon in May.
