10/11 – The Chief’s “More Humid Flow” Tuesday Morning Forecast
The pattern will moderate from the recent dry air pattern to a more humid flow through the day today. This morning, we will find clear skies and a quick warm-up will begin. Northeast winds will shift to southeast around 8 to 10 MPH by this afternoon and it will be in the low-to-mid 80s across the viewing area under partly cloudy skies. Tonight will see a notable uptick in humidity and cloud coverage will increase. A chance of showers in the overnight/predawn hours cannot be ruled out. Moisture from the Caribbean will quickly move into the area and that will keep our morning lows in the mid to upper 60s. By Wednesday morning, mostly cloudy and humid conditions will be the story. Daytime heating and increased lift ahead of a cold front will help fire off showers and thunderstorms throughout the day. Rain chances will be around 70%. The threat for heavy rainfall will be in the area along with pockets of flash flooding.
A cold front will move through the area on Thursday. There will be a chance of rain early on Thursday before the front comes through. The dry air will lag behind it and since the storm system is farther north and farther along in its life cycle, only a minor cool-down is expected. Morning lows will be in the upper 50s to around 60 Friday morning, and the afternoon highs will be in the low 80s. Following the cold front, a brief area of surface high pressure sits over the area on Friday and Saturday. This keeps conditions dry through most of the weekend, but surface flow quickly shifts to more southerly/southeasterly which helps re-introduce moisture in the area. Focus early next week begins to shift as surface front swing down into the lower Mississippi Valley region. As it stands right now, frontal passage will be Tuesday evening.
