DISCUSSION

A beautiful Friday has unfolded as sunny skies have allowed temperatures to rise into the 60s across most of the area. Even a few 70s have been observed in southern MN and western WI. It is a little breezy across WI, likely owing to the confluent surface pressure gradient. Clouds are in the process of moving in from the west, however, as our next shortwave arrives tonight. An isolated thunderstorm may occur later this afternoon across western MN but showers are expected to move in from west to east this evening through Saturday morning. They will eventually move east by Saturday afternoon, leaving the remainder of the weekend dry. CAMs have been picking up on the possibility of two heavier areas of rainfall, one from western to central MN and the other in southern to southeastern MN. In these locations, rainfall has a good chance of exceeding 0.5" while a minima of 0.1-0.2" would be in between. The southern band also looks to be convective in nature (judging from non-zero CAPE in RAP soundings) so perhaps a lightning strike or two could occur during Saturday morning. The rest of Saturday looks decent, albeit a bit cooler as clouds will be in the process of clearing. Highs are forecast in the upper 50s to lower 60s. Sunday still looks great with sunny skies, light winds, and highs in the mid to upper 60s.
Monday also continues to look warm (highs in the low to mid 70s)
but, chances for showers and thunderstorms will increase as we progress through the day. Ensemble guidance forecasts a very strong, negatively-tilted trough to eject east of the Rockies (and into the Southern/Central Plains) during Monday. An expansive, moist warm sector created ahead of the trough over the Plains should allow for widespread showers and thunderstorms to develop Monday afternoon into Monday evening. Forecast models show this activity extending all the way north into the Dakotas ahead of a cold front that stems from a deepening surface low in the Northern High Plains. This band of precip is forecast to move east through our region Monday night into Tuesday. While the strongest convection will likely be in the Central Plains, a couple of stronger storms will not be out of the question due to probable strong vertical wind shear and non-zero CAPE. How strong and numerous those storms are will be largely dependent on how much CAPE can be realized, though. The grand ensemble advertises another good chance of at least an accumulating, widespread rain. Western and southern MN currently have a 50% chance of seeing at least 1" of rainfall through Tuesday afternoon. Winds should also be very breezy Monday into Wednesday as NAEFS and EPS ensembles show the surface low deepening enough to achieve climatologically minimum mean SLP over the Northern High Plains.
After Tuesday, it seems like precipitation chances will persist for the majority of next week as the upper-level low cuts off and hangs out over the northern CONUS before moving east. We can expect at least periods of persistent clouds and cooler temperatures underneath the cool air of the cyclonic flow center.

VFR for all terminals to start while a cold front sits atop MN/WI. This front will become more active this evening through tonight as a disturbance aloft drifts southeast from southern Manitoba, helping spawn a swath of rain over the eastern Dakotas and western MN this afternoon. This swath will then slowly move east this evening through the overnight hours, bringing MVFR ceilings and visibilities to all terminals gradually from west to east. Chances for CB/TS are rather low, limited mainly to far southern MN (thus KMKT), so have opted to not include its mention in this set. Ceilings have the potential to drop to IFR but confidence not high enough to go that route. Rainfall looks to end around sunrise in western MN, by late morning in eastern MN and early afternoon in western WI. Winds will be breezy from the SW through this afternoon, then the progression of and convergence around the front will dictate winds through tonight before winds settle on northwesterly Saturday morning with speeds 10kts or less.
KMSP...Main issue through this afternoon will be breezy winds from the 210-230 range, potentially causing crosswind concerns for the parallel runways. Once past that issue, come later this evening when winds become northerly, rain looks to move in around 08z, potentially as early as 06z, and continuing through daybreak. Chances fairly low for CB/TS at this point but will continue to evaluate for inclusion later. Rainfall amounts look to run 0.25"-0.50". Clearing then expected from late morning onward with NW winds.
/OUTLOOK FOR KMSP/ SUN...VFR. Wind variable 5 kts becoming SE 5-10 kts.
MON...VFR. Chance PM MVFR/-RA. Wind SE 15-20G25-30 kts.
TUE...Mainly VFR. Chance MVFR/-TSRA. Wind S 15-20G25-30kts.
HYDROLOGY

The continued wet pattern for the next week will also continue to cause rising rivers over the entire HSA. Soils have started to become saturated at upper levels, so runoff is increasing with each rain event, though the onset of the growing season does help along with recovery days between rain events. All told, most tributaries and mainstem rivers will continue a slow rise for at least the next week, with some in the Minnesota and Crow river basins approaching minor flood stage by early next week (Minnesota at Morton already there).
