Our skies today have been a fast-moving mix of clouds, courtesy of a low pressure center in Nebraska, and wildfire smoke.
Some showers and thunderstorms developed over southwestern Minnesota during the heating of the day ahead of that low, but they have had difficulty advancing very far into our rather dry air. National Weather Service radar has been tracking them.
Showers and storms will become more numerous tonight as they track eastward mainly across the southern quarter of Minnesota. The Twin Cities are likely to be near the northern edge of the rain overnight and Friday morning, so any forecast amounts would be just a guess.
Severe weather is not expected. However, widespread rains of 1 to 2 inches are possible, even likely, across southern Minnesota by the time the rain ends from west to east on Friday.

In addition, as shown on the forecast map, a few thunderstorms could break out near the Canadian border Friday afternoon.
Saturday and Sunday look like they will make a lovely late-August weekend as long as you don't mind a warming trend.
Meanwhile, elsewhere
Tropical Storms Erika, with maximum sustained winds of just around 45 miles per hour, is preparing to exit the Lesser Antilles.
Erika is tracking a little farther south than was forecast. That puts the storm on a track to pass near St. Croix later today and then over Puerto Rico tonight.
Widespread rainfalls of 4 to 8 inches and some greater amounts are possible in Puerto Rico where, ironically, the island has been in severe to extreme drought this summer. A state of emergency was issued because of the drought and water rationing was initiated.
Erika will then cross over or near the Dominican Republic on Friday and head for the Turks and Caicos Islands and southeastern Bahamas on Saturday. All locations affected will get heavy rain.
The potential impact on Florida is still a question mark as Erika is likely to turn more to the north as it approaches the Sunshine State.
However, the farther-south track that Erika is taking makes it appear more likely that Florida will get at least sideswiped. The bulge in the Florida peninsula in the West Palm Beach area might appear to be a likely target on Monday but there is significant uncertainty at that time range.
Western wildfires
While the devastating wildfires in Washington state and northern California have received considerable press coverage, there also have been many fires in Idaho and western Montana.
Three fires have been underway for quite some time in my favorite national park, Glacier National Park in northwestern Montana. Thanks to the widespread smoke, the views toward Many Glacier Hotel (left), Mt. Gould and Grinnell Point do not present the clear, sparkling views that visitors to these glorious mountains would expect.
This and several other webcams in the park can be accessed from this link.
