Garrett’s Blog: September’s First Week
The first week of September will be characterized by small rain chances early, a calm high pressure ridge midweek, & eventual Labor Day cold front. Here’s a look at how the upper level winds will affect our weather over the next several days.
The strongest upper level support remains in Canada with hot and typical late-summer conditions prevailing across much of the southern United States.
Monday-Tuesday: A weak shear axis is located across parts of Texas and central Arkansas. This will give rise to a few showers and thunderstorms that develop with peak daytime heating. Overall coverage will remain limited.
Wednesday-Sunday: Strong high pressure continues to ridge north across the central United States. Expect temperatures to run near or above normal for the remainder of the week. Highs in Northwest Arkansas will be near 90º with highs in the Fort Smith area in the low to mid 90s. Strong south winds are likely heading into the weekend as the pressure gradient tightens up with the approach of the trough out west.
Labor Day: A weak cold front will move into the area sometime late weekend into next week. Currently, the data suggests it arrives on Labor Day which could feature much cooler weather and a chance for scattered showers and thunderstorms.
