DISCUSSION

Issued at 129 PM CDT Mon May 4 2026

An upper trough continues to dig into the northern Plains and Great Lakes regions through Wednesday. At the surface this translates to temperatures 15 to 20 degrees below normal for early May with lows in the 20s and highs in the 40s to lower 50s.

Northwest winds are gusting 35 to 40 mph this afternoon in the caa, enhanced by dry air and steep lapse rates in the low levels as evidenced by inverted V soundings. Precip on radar may result in a sprinkle at best, but more likely virga showers until sunset. Any elevated shower could mix down a stronger wind gust to around 50 mph if the shower collapses. Winds are expected to diminish after sunset as well before increasing again on Tuesday with gusts of 25 to 30 mph.

The dry and cool conditions persist into Thursday when waa pushes 850 mb temps back above +8C. Temperatures will likely be moderated somewhat, though, by northwest flow aloft and clouds in weak low pressure at the sfc. Expect to be closer to climo normal values by Friday when upper ridging tries to build in.
