Area Forecast Discussion National Weather Service Gaylord MI 941 PM EDT Mon Jun 14 2021
UPDATE. Issued at 941 PM EDT Mon Jun 14 2021
Cool Canadian high pressure continues to build into the Western Great Lakes late this evening. Residual moisture combined with diurnal instability and some lingering cyclonic flow resulted in spotty shower and thunderstorm development for areas along and east of I-75 this afternoon/evening. This convection has diminished and dropped south out of our CWA. Skies have become mostly clear across our entire CWA . and will remain so thru the overnight hours. Clear skies and diminishing winds combined with a rather cool airmass will allow overnight lows to drop into the upper 40s and lower 50s.
NEAR TERM. (Through Tonight) Issued at 328 PM EDT Mon Jun 14 2021
. Much cooler tonight .
High impact weather potential: Minimal. May see an isolated thunderstorm or two this afternoon, but nothing severe expected.
Pattern synopsis and forecast:
Pattern amplification talked about yesterday continues, driven in large part by strong anti-cyclonically curved upper jet streak extending from the Pacific Northwest to the western Great Lakes (bowing north into northern Canada). Upper level ridge south of this jet streak impressive to say the least, with nearly 600 decameter center near the Four Corners, with ridge apex extending north into the northern reaches of Saskatchewan. Downstream response is as one would expect, with deep troughing maturing across northeast NOAM, including the Great Lakes. Several waves embedded in attendant north flow aloft, with last nights rain-producing wave now well to our southeast, with secondary wave dropping south across the area early this afternoon.
Deep north flow will continue for the next several days, bringing will it sharply cooler conditions. Overhead shortwave will exit quickly south of our area this evening, leaving behind dry conditions tonight.
Primary forecast concerns/challenges:
Addressing any shower/storm threat the remainder of this afternoon and overnight temperature trends.
Details:
Still expecting to see some isolated showers and thunderstorms across parts of northeast lower Michigan this afternoon as mixed layer cape profiles approach a few hundred joules/kg and with no convective inhibition. Any showers will come to a quick end this evening as shortwave support is lost and instability wanes. Clear to partly cloudy skies expected overnight. North winds will continue to usher in a progressively cooler airmass, helping drop temperatures into the upper 40s to middle 50s (actually about normal for this time of year).
SHORT TERM. (Tuesday through Thursday) Issued at 328 PM EDT Mon Jun 14 2021
. Cooler, drier weather ahead .
High Impact Weather Potential: Fire weather concerns
Pattern Synopsis:
Impressive ridging centered over the 4 Corners will continue to amplify into Canada into midweek as troughing dips across the Great Lakes and NE CONUS. This amplified ridging will slide over the region on Thursday as a seasonably strong closed upper-level low will trek from the Pacific NW into the northern Great Plains. Surface high pressure will build from Hudson Bay into the Great Lakes by Wednesday underneath subsidence aloft.
Forecast/Details:
Beautiful weather is expected across northern Michigan through the middle of this week. Surface high pressure in Canada will result in light northerly low-level flow across the area through Wednesday, helping to keep cooler, drier air in place. While expected highs in the low to mid 70s will be close to normal, it will feel much cooler after the very hot start to June. The dry airmass in place will lead to sunny/clear skies, precip-free weather, and fire weather concerns in areas of northern Michigan that haven't experienced much rainfall to start the month. With clear skies and weak winds as high pressure moves overhead, some chilly overnight temps are expected Tuesday night. Lows may dip into the upper 30s in some places across interior portions of the area. Afternoon highs should warm back up into the 80s on Thursday.
LONG TERM. (Thursday night through Monday) Issued at 328 PM EDT Mon Jun 14 2021
High Impact Weather Potential: Low for now
A seasonably strong shortwave is expected to progress from the northern Great Plains over the Great Lakes by Friday night, providing support aloft for a cyclone that should trek across Ontario into Quebec. Mainly zonal upper-level flow is expected over the region heading into next week. The main focus will be the arrival of our next rain/thunder chances Thursday night. Current thoughts are that a line of showers and storms will initiate west of Lake Michigan Thursday afternoon and progress into Michigan during the overnight hours. Confidence isn't overly high in the CWA experiencing storms specifically, but many areas will at least have the chance to see rain. Additionally, a second round of showers/storms may initiate Friday afternoon across the area as prime forcing aloft from the shortwave moves overhead and before the main front slides through the state. This is highly dependent on the timing of the system, but the potential exists. If this is the case, ample shear aloft would be in place to support stronger storms, but instability would be the main question. Otherwise, highs in the low 80s are expected heading into the weekend before cooler temperatures arrive for the weekend following the frontal passage.
AVIATION. (For the 00Z TAFS through 00Z Tuesday evening) Issued at 713 PM EDT Mon Jun 14 2021
Cool Canadian high pressure will continue to build southward into the Western Great Lakes thru Tuesday night. Residual showers and VFR CU will dissipate with loss of diurnal instability this evening . leaving clear skies and VFR vsbys thru tonight and Tuesday as subsidence further strengthens. Surface winds will remain northerly and diminish to around 10 kts after sunset tonight . and the strengthen again on Tuesday to 15 to 25 kts.
MARINE. Issued at 328 PM EDT Mon Jun 14 2021
Northwest winds expected to veer more northerly late tonight and Tuesday. Wind gusts will increase some on Tuesday, perhaps reaching small craft criteria on some nearshore waters. North winds slowly decrease in speed Tuesday night. Other than a few spotty showers this afternoon, dry and cooler weather will prevail.
