Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 252 PM CDT Thu Oct 21 2021

SHORT TERM. (This evening through Friday night) Issued at 252 PM CDT Thu Oct 21 2021

We will see some lingering clouds this afternoon to early evening associated with the low that provided yesterday's rain. With high pressure moving in now the forecast is trending towards clear sky and light winds with little chance for any precipitation. The main impact this evening through Friday night will be the cold temperatures. With both overnights expected to have temperatures fall near to below freezing. While we are past the 90th percentile of first freeze dates for our area this could be the first hard freeze chance this fall for many locations across southern Minnesota and west central Wisconsin. Having a first freeze this week is more typical of Tennessee or Arkansas than Minnesota and Wisconsin!

We could see a chance for some sprinkles or even flurries in parts of west central Minnesota late tonight into early tomorrow morning associated with a short wave aloft. With limited low level moisture this is not likely, but with the chance for some to see their first snow flakes of the season it is worth bringing up. If sprinkles or flurries occur a trace is expected with no accumulation.

LONG TERM. (Saturday through Thursday) Issued at 252 PM CDT Thu Oct 21 2021

It’ll be a frosty start for all but the inner Twin Cities metro Saturday morning. Surface temperatures should range from the upper 20s to low/mid 30s in the inner metro. Afternoon temperatures recover with highs in the upper 40s to lower 50s and partly cloudy skies are expected, but the pleasant fall weather will not last! A shortwave trough tracks across the central CONUS, placing a thermal gradient over the MPX forecast area. Showers are expected to develop across southern Minnesota Sunday morning and expand northward throughout the day. Non-GFS model guidance is further south with the heaviest QPF amounts across central and northern Iowa. As such, the NBM keeps 50 to 60 PoPs from the Twin Cities southward Sunday afternoon. Forecast soundings hint that some snow could mix in after sunset across our northwestern counties in central Minnesota. Surface temperatures should remain warm enough so any accumulation is not likely.

Monday through Wednesday night, dry conditions return for the start of the week as an upper level ridge builds in from the western CONUS. After Monday, the model guidance begins to diverge in how to handle an upstream trough that is expected to push into the central CONUS for mid week. Some guidance is much cooler for this period than previous runs, but the NBM continues forward with high temperatures in the lower to mid 60s for Tuesday and Wednesday. A cold front associated with the trough feature will bring another round of precipitation on Wednesday That being said. there is a fair bit of uncertainty in the evolution of this feature and it will be closely monitored.

AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1220 PM CDT Thu Oct 21 2021
