UPDATE. Issued at 555 AM CDT Tue Sep 28 2021
Updated to include 12Z aviation discussion below.
SHORT TERM. (Today through Wednesday) Issued at 229 AM CDT Tue Sep 28 2021
Quiet weather will persist through the short term as high pressure centered over the Great Lakes slowly moves east. Upper ridging will remain in place across our area as a surface trough very slowly begins to emerge from the Plains tonight and Wednesday. Return flow and increased moisture could bring some precipitation to the far western portion of the area by late Wednesday afternoon, although guidance has understandably been slowing things down. Temperatures will be well above normal today and Wednesday with most locations expected to top 80 each day.
LONG TERM. (Wednesday night through Monday) Issued at 229 AM CDT Tue Sep 28 2021
Warm and dry weather will continue to be the dominating conditions for the first half of the long term period. The main culprit is an amplifying ridge that'll stretch from the Central Plains northward into central Canada. This will allow temps to return to the 80s on Thursday and mid 70s on Friday before a weak cold front swings through. Low temperatures will be in the lower 60s and upper 50s initially, before returning to near normal late this weekend.
Toward the end of the week, the combination of a nearly stationary broad trough and upper level low downstream over the Canadian Maritimes and an approaching shortwave lifting northeast out of the Central Rockies and east across the northern CONUS look to squeeze and then deamplify the ridge. Similarly to yesterday night, this evening's 00z guidance lifts a surface front up the ridge's western periphery Thursday afternoon. The model consensus appears to move the front into western Minnesota before crawling eastward into Friday. The NBM retains a long duration of slight and chance PoPs from Thursday morning through Sunday afternoon. This is due to the spread in model and ensemble members solutions beyond Friday. Majority of the long term forecast period will remain dry. The best bet for precip in the Twin Cities Metro will be Thursday evening to Friday morning with the frontal passage. Beyond that, there's still not a clear picture on the pattern evolution.
Given the uncertainty in this pattern and that of an upper level low ejecting out of the four corners region, the track and evolution of subsequent systems for the remainder of the long term is also uncertain.
AVIATION. (For the 12Z TAFS through 12Z Wednesday morning) Issued at 555 AM CDT Tue Sep 28 2021
High pressure over the Great Lakes will slowly move east through the period as a weak surface trough over the High Plains begins to approach from the west. VFR conditions will persist, along with mainly light southeast winds.
KMSP . No concerns or meaningful uncertainty through the period.
/OUTLOOK FOR KMSP/ Wednesday afternoon through Thursday . VFR. Southeast wind 5 to 15 kt. Thursday night . MVFR possible with a chance of SHRA/TSRA. South wind 5 to 15 kt becoming east. Friday Friday . MVFR expected, IFR possible with a chance of SHRA/TSRA. East wind 5 to 15 kt becoming northeast.
MPX WATCHES/WARNINGS/ADVISORIES. MN . None. WI . None.
