Our gloomy morning and midday transformed into a much brighter afternoon. Temperatures responded by warming well into the 70s. Winds from the south keep it feeling summery into Friday afternoon.  But a strong cold front crashes the party by Friday evening, with a round of heavy showers and storms.

Through Tonight:  It’s very pleasant to be outdoors with a soft breeze from the south and mild temperatures.  There may be a bit of fog late at night, with lows from 58-64 (suburbs-city).

Tomorrow (Friday): Partly sunny into the afternoon and warm.  A wind from the south at 10-20 mph elevates temperatures to near 80, and you’ll notice a touch of humidity.

Between 5 and 10 p.m., a line of showers and thunderstorms moves into the region, likely accompanied by gusty winds, heavy rain, thunder and lightning.  The storms should exit the region after 1 a.m.  The risk of severe weather (damaging winds and/or large hail) is low, but cannot be entirely ruled out.  We’ll have more details tomorrow.

Climate: NOAA announced today that this past March was  the 10th warmest on record globally since 1880. “It also marked the 37th consecutive March and 337th consecutive month with a global temperature above the 20th century average,” its report says. The U.S. was cooler than average, but was an exception rather than the rule globally as NOAA points out in this video: Pockets of cold in a warming world

Snow/cold in Minnesota: Believe it or not, it’s snowing in Minneapolis, and a winter storm warning is in effect there through Friday morning for 6-9 inches.  Ironically, Minnesota was running tornado drills today.
