UPDATE. For 12Z Aviation discussion below
SHORT TERM. (Today through Saturday) Issued at 408 AM CST Fri Mar 5 2021
No change with the expectation of mild and dry weather into the weekend, as western CONUS mid-level ridging continues to build eastward, and high pressure remains in tact at the surface.
In the near-term, mid-level clouds have formed in the vicinity of the high pressure surface ridge bisecting the forecast area. Said cloud cover has limited fog development overnight, with the exception of far west central MN where clear skies and calm winds have allowed for patchy development. The cloud cover looks to linger through the morning, which could slow diurnal warming somewhat, but lower 40s/50s like we saw yesterday seem achievable.
Fog and stratus development will be possible tonight into Saturday morning as we see continued increasing boundary layer moisture with snowmelt, combined with light winds. Therefore, despite the fact that 925-850mb temps moderate +2C degrees from today into Saturday, will take a conservative approach with forecast highs and stick to the low 40s to low 50s range for highs.
LONG TERM. (Saturday night through Thursday) Issued at 408 AM CST Fri Mar 5 2021
Temperatures continue to warm through early next week as 850 mb WAA into the Central and Northern Plains builds upper-level ridging over the central CONUS. With temperatures the last few days overachieving and NBM's cold bias prevalent into early next week, had good confidence to bump up highs Sunday thru Tuesday to nearly match the previous shift. Sunday and Monday, highs are forecast in the upper 50s to lower 60s for south-central MN. West-central WI will remain slightly cooler in the mid-50s. Overnight lows look to eclipse our normal highs this time of year Tuesday and Wednesday morning with most of the CWA struggling to drop below 40. In fact, Tuesday is forecast to be the warmest day of next week, though, latest guidance has trended slightly cooler. This is due the expected arrival of a 500 mb trough on the west coast slowing down and becoming more positively tilted. In consequence, decreased low-level WAA occurs into the Northern Plains allowing the aforementioned upper-level ridge to flatten earlier. Still, daily high temperature records will likely be broken Tuesday with low to mid 60s expected for highs. For reference, MSP's record high for March 9th is 61 and their forecast high for Tuesday is 66.
Precipitation chances return Tuesday night into Wednesday as a southwest to northeast oriented frontal zone and southwesterly upper-level jetstreak encroach our region. With decent agreement between the GFS, ECMWF, and GEM and a possibly coupled jet, have increased PoPs and added some thunder to the grids. Thus, we may see our first thunderstorms relatively early this Spring. Temperatures decrease the latter half of next week as the front pushes east through MN/WI Wednesday, bringing our warm spell to an end. Temperatures appear to hover near normal past the end of the period. Whether or not we get more precipitation is another question. A slight signal for increased precip exists in the long-term, though, more certainty would be nice in hopes to negate our region's current drought.
AVIATION. (For the 12Z TAFS through 12Z Saturday morning) Issued at 449 AM CST Fri Mar 5 2021
The area of mid-level clouds over eastern MN and west central WI will be slow to erode today with the surface ridge in place. Will delay the scattering of the deck until this afternoon. Tonight into Saturday morning looks to have a higher chance of stratus/fog development, so have included an IFR/MVFR mention at most sites toward daybreak Saturday. Winds will remain light east/southeast to calm through the period.
KMSP . Fog/stratus development for early Saturday morning is of low confidence, but given the trends of hi-res models, felt a mention was warranted.
