Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 253 PM CDT Sun Apr 18 2021

SHORT TERM. (This evening through Monday night) Issued at 253 PM CDT Sun Apr 18 2021

The key messages of the short term forecast center around the strong cold front that will through the region this evening. Temperatures are in the 60s ahead of the front with southwest winds and mostly sunny skies, but temperatures are in the 30s behind the front with northerly winds and cloudy skies. An area of rain/snow showers is ongoing just behind the front.

Today and Tonight - No significant changes to the forecast, as the timing of the frontal passage remains fairly consistent. Did trend back the pops a bit slower since they are lagging the surface front. The precipitation is quite intense, and that is leading to cooling and snow across northwest Minnesota. For us, we'll be warmer to start, and the precipitation should focus more across Lake Superior, so we shouldn't see the intensity and therefore expect mainly rain showers. This could mix in with snow across southern Minnesota later tonight, but no accumulation is expected.

Monday and Monday Night - Cold air advection will continue for Monday and that will keep temperatures in the 40s for highs. In fact some locations north of I-94 could stay in the upper 30s. Winds will be brisk, out of the northwest around 15 mph with gusts near 20 mph. This type of set up usually yields some rain/snow showers, but the post-frontal air mass is so dry that the forecast soundings only show a shallow layer of clouds. The HRRR does have showers mainly east of I-35 during peak heating, so did add some sprinkles across western WI. These will quickly dissipate after sunset, and then expect clearing skies with lows in the 20s across the region. It is too early in the growing season for any frost/freeze headlines, but this certainly looks like a hard-freeze with several hours below 30 degrees.

LONG TERM. (Tuesday through Sunday) Issued at 253 PM CDT Sun Apr 18 2021

A trough moving across Minnesota will start off the long term period on Tuesday. Our temperatures will remain cool with highs only in the 40s, but overall we should remain dry as this feature will not have much moisture to work with. The highest chance for precip will remain to our south. This reinforced shot of cooler air will stick around through Wednesday, however, it should be at least a few degrees warmer than Tuesday thanks to clearing skies. Ridging moves in by Thursday, allowing temperatures to return to seasonable normals in the upper 50s and low 60s.

The forecast is a bit less certain heading into Friday through the remainder of the period, but it appears that this will be our window for our next chance for precip. Guidance depicts a shortwave moving across Iowa Friday, leading to a chance of showers across central and southern Minnesota and western Wisconsin. Inconsistencies exist with the timing and strength of a cold front late Friday into Saturday, so have opted to leave the NBM as is until there is a better consensus.
