4th of July Weather Details
Friday: Partly sunny skies (high clouds dimming the sun by afternoon).

WRF/NAM computer model prediction for 7 pm Saturday, the 4th of July, hinting at generally dry weather for the eastern half of Minnesota, including St. Cloud, the Twin Cities, Duluth and Rochester, with scattered T-showers over western counties, maybe some strong/severe storms over the Red River Valley.
So, with all humility and caution I can predict a fairly nice holiday weekend for us, not "perfect", but pretty darn good for the biggest holiday weekend of summer. The weak ridge of high pressure floating overhead will keep us sunny and beautiful today with light winds, highs in the upper 70s to near 80. No complaints at all. Tomorrow an area of showers/storms over the Dakotas will brush far southwestern Minnesota, spreading high clouds into St. Cloud and the Twin Cities, dimming the sun, but any rain will probably stay south of the Minnesota River.
On Saturday, the 4th the sun should be out much of the day, but computer models are still hinting at a few PM showers and T-showers, most likely north/west of St. Cloud, toward Detroit Lakes, Cross Lakes and Bemidji - maybe some strong/severe storms up in the Red River Valley. The computer models keep much of central and southeastern Minnesota dry, with highs in the mid 70s to near 80 once again.
Sunday, the 5th, looks more unsettled, with more numerous showers and T-storms, affecting more than 50% of the state with a few hours of rain. The models print out .30 to .45" of rain Sunday. Where it rains temperatures will hold in the low and mid 70s. Where the sun is out most of the day the mercury may hit 80, with more humidity, winds still fairly light on area lakes.
Today: Sunny and gorgeous. Little wind, low humidity, postcard-pretty. Winds: NW 5-10. High: 79
Tonight: Clear and cool. Low: 56
Friday: Dim sun through high clouds, probably dry. Sunnier north, cloudier south. Showers over far southwestern MN. High: near 80
Saturday (4th): Mix of clouds and sun, slight chance of a PM T-shower. More numerous storms far north and west. High: 80
Odds favor dry weather for most of us Saturday night, temperatures around 70 when the fireworks go off around 9:30-10:00 pm
Sunday: Mostly cloudy, unsettled, a few hours of showers, T-storms. A few downpours possible. High: 78
Monday: Plenty of sun, seasonably mild. High: 82
Tuesday: Early shower, then increasingly sunny and warm. High: 85
Wednesday: Hazy sun, almost hot! High: 88
Low 90s possible the latter half of next week. Yes, next week will definitely look and feel more like typical July weather.
