Fxus63 kapx 250349 afdapx area forecast discussion national weather service gaylord mi 1149 pm edt Sat aug 24 2019 Update Issued at 931 pm edt Sat aug 24 2019 a little cirrus wafting in from the north this evening, just in advance of the 500mb ridge axis drifting eastward. Some minor tweaks to cloud cover to account. Otherwise very quiet. Light easterly synoptic wind will contribute to moistening into NE lower mi. That area will be prone to some fog and perhaps stratus overnight into Sunday morning. Going forecast has that covered well. As for temps, 40s to around 50f will be most common, but the cold spots will dip down into the 30s again. Near term (through tonight) issued at 345 pm edt Sat aug 24 2019 Quiet and cool again tonight... high impact weather potential: minimal. Some fog status possible overnight. Pattern synopsis forecast: afternoon analysis reveals a sharp short-wave ridge axis from the midwest up through the far western great lakes, part of a pseudo omega block pattern across the region. Strong surface high pressure is centered just northeast of state with easterly flow cycling cool dry air through the region. We have seen some heating of the day CU develop across inland areas, although overall sunny mostly sunny skies are the rule. Primary forecast concerns: overnight lows and fog stratus potential. Sharp short-wave ridge and surface high pressure will edge off to the east tonight while our low level flow veers southeasterly and increases just a bit. Heating of the day CU fades early this evening leading to clear skies and another good radiational cooling setup. That said, moderating low level temperatures and the slight increase in low level flow may counteract radiational cooling to some degree particularly across the western part of the forecast area. So for tonight... I have the coolest overnight lows across interior eastern upper and northeast lower michigan with those areas dipping into the upper 30s to lower 40s while acknowledging that we will probably have a few spots dip into the middle 30s once again (atlanta, mio, etc). Fog stratus: given our afternoon min dewpoints (crossover temps) of 45 to 50, anticipated lows and a decoupled boundary layer, some fog seems reasonable, especially across eastern upper and ne lower michigan where the lowest temps are anticipated. Eventual low level SE warm moist flow off lake huron overtop a cool boundary layer may add to the fog or even stratus potential. Will see. But i have added patchy-areas of fog to the forecast as well as some increasing cloud cover (stratus) toward morning. Short term (Sunday through Tuesday) issued at 345 pm edt Sat aug 24 2019 A better chance for rain on Monday night Tuesday?... high impact weather potential... Thunder possible Monday evening. Pattern synopsis forecast... High pressure over the upper great lakes begins to slip east, allowing the return flow to move into the state. Winds will increase as the pressure gradient tightens. This will lead to stronger winds near the straits, initially, but then spread across the region Monday afternoon, as the warm front passes through lower michigan. Rain showers are expected in the afternoon,

but the main precipitation comes in Monday evening (after 00z tue) as a 500 mb shortwave moves into the region with the front. The cold front and the sfc trough, associated with the sfc low move through by 12z Tue bringing rain showers, and maybe some thunder. The rain looks to clear out by Tuesday afternoon as some shortwave ridging and dry air quickly noses into the region. Primary forecast concerns... This could be the best chance for rain that we have seen in a while. However, as we have seen in the past few weeks, the models have been having trouble with the frontal passages. However, this looks to be more a concerted effort for the 500 mb low and jet to sink into N plains and the upper great lakes. Since we are beginning to head into the fall season, this does look to be more a fall type system. The 850 mb temperatures associated with this system(upstream) are in the mid single digits so there is better certainty with this system. Long term (Tuesday night through Saturday) issued at 345 pm edt Sat aug 24 2019 high impact weather potential... Minimal extended (Tuesday evening through Saturday)... After the brief warm up for early part of the week, as the we get into the middle of the week, there is a cooling trend with the long wave pattern. A decent 500 mb low drops south into NW ontario, just west of james bay, on Tuesday night, which looks to brings with it 850 mb temperatures that are sub +5c. As that air and the sfc low moves into lake superior, +6c +7c air moves over lake michigan and its +21c water temperatures. We may be looking at le rain possibilities for Wednesday and Wednesday night, before high pressure and dry air Thursday move in. However, there are some timing issues with the gfs and ECMWF so that small rain chances continue through Thursday and Friday. Friday night and Saturday, high pressure builds into the region and it looks like it dries out again. Aviation (for the 06z tafs through 06z Sunday night) issued at 1149 pm edt Sat aug 24 2019 ifr fog at pln apn overnight. High pressure will slowly move east from the eastern lakes, but will continue to extend ridging into northern mi. Our wx will remain quiet. Only really concern is for any fog stratus late tonight. Fog appears most likely at apn pln, near the moistening influence of lk huron. Ifr conditions expected at times late tonight and early Sunday morning. OtherwiseVFR. Light winds tonight, a bit of a SE breeze Sunday. Marine Issued at 345 pm edt Sat aug 24 2019 light winds and waves anticipated tonight. Some SE gustiness develops on Sunday and it might be enough to consider small craft advisories up through the straits. But stronger flow comes on Monday and it appears that small crafts will be needed for many nearshore areas at that time. Weather-wise, quiet tonight through Sunday night. Shower chances return Monday. Apx watches warnings advisories Mi... None. Lh... None. Lm... None. Ls... None. Update... Jz near term... Ba short term... Jl long term... Jl aviation... Jz marine...
