DISCUSSION

Issued at 227 AM CDT Sun Sep 6 2026

The northeast winds are developing southward early this morning, as surface high pressure begins to build through the Quad State. However, the cooling and drying surge seems a bit slow to arrive. The NBM has trended back up with temperatures and heat indices today. Therefore, we have added a handful of counties to today's Heat Advisory. It now roughly covers the area south of a Greenville Missouri to Murray Kentucky line. This should be the end of the heat headlines for a few days, if not a significantly longer period.

The less hot temperatures and low dewpoints in the upper 50s are still expected across the entire region for Labor Day. Unfortunately, the upper ridge will begin to build back over the Quad State Monday and south winds at the surface will return on Tuesday. This will lead to another warming trend Tuesday through Wednesday. Temperatures will climb back into the middle 90s Tuesday and the 95-100 degree range Wednesday. Dewpoints will rebound into the 60s, but even on Wednesday heat indices will only reach the 100-105 range, which would not require a Heat Advisory.

The ridge will give way to weak zonal flow allowing a cold front and with a decent chance of showers and thunderstorms to move through the Quad State at some point Wednesday night into Thursday. The NBM currently has PoPs ranging from 30% in the south to 50% in the north. While there is QPF throughout the region, it is generally a half inch or less, which is not exactly going to reverse our current dry spell.

The weak zonal flow aloft will continue Friday through next weekend. Temperatures will trend back to normal or just slightly above. The zonal flow aloft will seriously muddle the precipitation chances and timing. For now, the NBM has small chances nearly everyday.

Some high cirrus may move across the area overnight, but otherwise skies should be clear tomorrow morning.
