(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kapx 180249 afdapx area forecast discussion national weather service gaylord mi 949 pm est Sun feb 17 2019 Update Issued at 949 pm est Sun feb 17 2019 low pressure continues to make its way NE thru the ohio valley late this evening..With a secondary low centered over central illinois. Elongated area of mainly light snow continues to develop north of this system... Now impacting northern illinois... Southern wisconsin and central and southern lower michigan. Northern edge of this snow shield continues to produce some light snow for portions of our southern cwa... With only some additional low and mid cloud cover for the rest of our cwa. Both areas of low pressure will continue to push eastward toward the atlantic coast overnight. Light snow will come to a gradual end across our southern cwa... But diminishing cloud cover will likely hold off until Monday. Latest kapx base ref trends are already beginning to show some diminish in returns. Expect little in the way of new snow accumulation overnight. Cold temps will continue... With overnight lows mainly in the single digits... With some isolated colder spots expected. Near term (through tonight) issued at 243 pm est Sun feb 17 2019 high impact weather potential: none. Pattern synopsis forecast: early afternoon composite analysis shows iowa centered shortwave trough steadily shearing out as it heads into great lakes centered mid level confluence axis. Broad area of mostly light snow tied to this shortwave, extending from the upper mississippi valley into the southern great lakes. Some of this snow trying mightily to punch into our southern areas, although without too much success as dry northeast flow rotating around elongated southern canada high pressure is keeping much of it from reaching the surface. Otherwise, another uneventful day (2 in a row!!), with plenty of clouds and some lake induced flurries rotating off northern lake huron. Iowa shortwave will continue to shear out tonight as it heads across the southern great lakes. While this system will clip southern areas will a bit of very light snow, than canadian high pressure will exert much more influence, keeping much of the area dry and seasonably chilly tonight. Primary forecast concerns challenges: addressing snow evolution and amounts, primarily late this afternoon and evening. Overnight cloud and temperature trends. Details: a battle of opposing airmasses, with that dry northeast flow largely winning the battle later this afternoon and overnight. Pattern recognition and guidance derived sounding analysis both suggest snow will have a real struggle reaching the surface north of m-72, with only somewhat better further south. Both very weak forcing and limited moisture suggests any snow that does fall will be light, with accumulations likely remaining under an inch. Given what we have gone through, definitely not a big deal at all. Will also likely see a few lake huron induced flurries rotating into northeast lower michigan, with mostly cloudy but dry conditions prevailing elsewhere. Those clouds and maintenance of northeast surface winds will keep temperatures a smidge warmer than those observed this past night, with readings mostly in the single digits and teens. Of course, those winds will make it feel a few degrees colder. Short term (Monday through Wednesday) issued at 243 pm est Sun feb 17 2019 high impact weather potential: minimal. Pattern synopsis forecast: expansive high pressure drifting across the great lakes Monday through Tuesday is expected to lead to fairly tranquil conditions across the forecast area, although sufficient over-lake instability may yield some light lake effect snow showers flurries Monday evening into Tuesday across portions of northwest lower and eastern upper, despite rather limited moisture fields. Attention then shifts to the Wednesday time frame as a mid- level wave and developing area of surface low pressure trek from the mid-mississippi valley toward the lower lakes ohio valley region, |
likely bringing a period of accumulating snow to much of northern michigan. Primary forecast concerns challenges: light lake effect chances through Tuesday. Snow chances amounts Wednesday. Anomalously strong high pressure is expected to slide across the region during the day Monday as Sunday night's system focused to our south shifts off to the east. Northerly flow will bring a marginally colder airmass to much of northern michigan through the day Monday, evident by h8 temps falling to near -16 c by Monday afternoon. However, anemic moisture, sub 3 kft inversion heights and weakening backing wind fields should prevent anything more than nuisance flurries or light lake effect snow showers from developing. This would affect mainly N nnw flow snow belts of both lake superior and michigan, but certainly doesn't look like anything impactful. By Monday night, high pressure slides overhead allowing boundary layer winds to decouple resulting in perhaps some enhanced convergence along the lake michigan and superior coastlines, marginally enhancing light lake effect snow showers for a period of time late Monday night into Tuesday morning. Given continued weak wind fields, any snow showers should remain limited near the coasts and nothing of real impact as moisture continues to look rather paltry by late Tuesday afternoon, low-mid level warm air advection is expected to be underway ahead of the next approaching system, set to cross the region Wednesday into Wednesday evening. A developing surface low is expected to trek from the south-central plains into the great lakes, spreading mainly light snow from southwest to northeast across the region beginning early Wednesday morning across our southwestern counties before spreading northeastward toward far nw lower and eastern upper by midday. Model consensus QPF generally ranges from 0.20-0.30 inches resulting in a general 2-4 inches of accumulation... Highest across the tip of the mitt into eastern upper where more robust forcing is expected Wednesday afternoon. Would expect some refinement to snowfall accumulation and timing over the next couple of days. Not nearly as windy as the past couple of systems with south-southeast winds gusting up to 15 mph during the day Wednesday. Snow tapers off Wednesday evening into early Wednesday night as the system begins to exit the region to the east. High temperatures Monday ranging from the middle teens to the lower 20s area wide before consistently warming a couple of degrees each day through Wednesday. Wednesday's highs expected to vary from the mid-upper 20s across the forecast area. Long term (Wednesday night through Sunday) issued at 243 pm est Sun feb 17 2019 high impact weather potential: minimal for now. Perhaps some lingering light lake effect snow showers at times Thursday into Friday, although limited moisture and over-lake instability would suggest nothing of impact. The next chance for widespread snow arrives Saturday as another system ramps up across the midsection of the country before trekking northeastward toward the great lakes. Much uncertainty exists during this time frame, but bears watching moving forward. Aviation (for the 00z tafs through 00z Monday evening) issued at 609 pm est Sun feb 17 2019 low pressure will continue to track thru the ohio valley this evening... Moving into the NE us overnight and Monday. Northern edge of the associated moisture shield will remain over northern lower michigan this evening and will then begin to pull eastward as the low departs. LowVFR high MVFR CIGS will hold over our region tonight... Along with a small chance of snow showers thru the evening. Clouds will diminish on Monday as high pressure and drier air build back into the western great lakes region. NE winds aob 10 kts tonight will become northerly on Monday.
