Preliminary data indicated April began by setting two new state temperature records: 90 degrees F at Luverne on the 1st; and 88 degrees F at Pipestone on the 2nd. In addition a Maplewood phenology observer reported seeing dandelions on April 2nd, one of the earliest dates ever.
Lake ice-out dates this spring have set new records for earliness all around the state. A summary of this can be found at the DNR set site. Despite the temperature and phenology records frost is a definite part of the weather mix for early next week and red flag warnings may continue for parts of the state due to low humidity, strong winds, and risk of fire danger.
A few good April showers would be welcome before farmers begin planting the state's corn crop on April 11th (the activation date for crop insurance). You can read more weather analysis in MInnesota WeatherTalk Newsletter this week. Keep the sweaters, sweatshirts and jackets handy for the Easter weekend.
The pink color indicates the region experiencing the lowest humidities and the highest winds this afternoon. Southwest Minnesota has also been missing out on spring showers as well. Since March 1st, Sioux Falls is about 1.50 inches below normal on precipitation.
A Red Flag Warning continues for the highlighted region through the remainder of the afternoon until the relative humidity comes up around sunset. At 3PM the relative humidity was a mere 16 percent along with wind gusts above 30 mph at Morris.
Plenty of sunshine graced Minnesota today with temperatures rather delightful, running close to ten degrees above normal. It was in the lower 60s in northern Minnesota at mid afternoon.
A cool front will slice through the state on Saturday, but does not promise to deposit much in the way of needed moisture. The GFS model indicates precipitation amounts are likely to be less than a tenth of an inch in most places.
Easter Sunday may turn out to be okay, but indeed cooler and on the breezy side. The really chilly air arrives overnight on Sunday.
Maximum temperatures on Sunday afternoon.
Some of the coldest air we've seen in four weeks will settle over the upper Midwest on Monday through Wednesday. High temperatures are expected to be several degrees cooler than the normal upper 40s and middle 50s from north to south. Frosty conditions are possible on Tuesday and Wednesday mornings.
