Meanwhile... Low pressure continues to gain strength to the lee of the rockies in the central plains. NE edge of mid and upper level moisture clouds from this system is pushing into the western great lakes region attm... With associated areas of synoptic snow extending from the dakotas thru northern minnesota into portions of wisconsin. Closer to home... All is generally calm... Mainly clear and very cold with temps generally in the single digits above and below zero. These mid and high clouds will spread into our CWA overnight as low level winds shift to the south and weak WAA commences. Small chances of snow will develop very late tonight into Tuesday morning as the initial waa wing warm front slides NE thru our cwa. Still appears better chances of accumulating snow will develop from west to east Tuesday afternoon as deeper moisture arrives ahead of the surface system. This will keep temps from tanking again overnight... With temps actually rise a few degrees as clouds overspread the area and southerly flow strengthens ahead of the plains low. Near term (through tonight) issued at 356 pm est Mon jan 21 2019 A bit of a moderating trend... high impact weather potential: none. Pattern synopsis forecast: center of arctic high pressure, responsible for the dangerously cold conditions of late, now pushing off to our southeast, with parent mid-level ridge axis just now building into the region. After early morning temperatures that where well below negative 20f in our traditional colder locations, gradually development of south return flow and plenty of sunshine has "boosted" readings into the single digits and lower teens early this afternoon. Of course, those same light winds make it feel just a bit colder, with wind chill values generally in the single digits. Both the surface and upper level flow regime remain quite progressive tonight, with surface high pressure pushing off to the east coast while mid level ridge axis builds into and through the northern great lakes. This results in further maturing of warm air advection, keeping overnight lows several degrees "warmer" than previous nights, and even bringing the possibility of a little light snow toward Tuesday morning. Primary forecast concerns challenges: cloud temperature trends and addressing that late night light snow potential. Details: south winds will be on the increase tonight as pressure gradient increases between departing surface high and developing southern plains low pressure. Increasing warm air advection through the column will result in slow top-down saturation, bringing slowly increasing and lowering clouds with it. Saturation looks to become deep enough to generate a bit of light snow late tonight, although as previous forecaster mentioned, gotta wonder if guidance is simply too aggressive with this idea given such a dry overhead airmass. Any snow that does fall will remain light, with amounts under an inch. Combination of those winds and increasing clouds will really prevent temperatures from falling too much tonight, and may actually see temperatures start to rise very late tonight. Expect lows generally in the single digits, although areas in the au sable river valley will likely dip several degrees below zero quickly this evening before recovering some later tonight. Wind chills will remain quite cold, in the single digits to teens below zero. Not headline worthy, but make sure you take proper precautions if venturing outside overnight. Short term (Tuesday through Thursday) issued at 356 pm est Mon jan 21 2019 Not as cold with widespread snow... |
high impact weather potential... Fairly high. Primary forecast concerns... Snow accumulations late Tuesday into early Wednesday. Low pressure emerges out of the central plains tonight, heads northeast and tracks across northern lower michigan Tuesday night into Wednesday morning. There will be strong warm advection isentropic upglide in advance of this system. Models have come into decent agreement with snow amounts. Forecast accumulations will generally range between 6 and 8 inches across eastern upper (enhancement due to a possible frontogenetical band) and 4 to 6 inches across northern lower (highest near the staits and lowest across southeast counties where a little rain could mix in). Headlines will likely be advisory level but will defer this decision to the midnight shift as the bulk of the snow will not fall until the third period of the forecast (Tuesday night into easy Wednesday). It then looks like some north northwest flow lake effect snow showers during the day Wednesday with a break in the action expected Wednesday night. Long term (Thursday night through Monday) issued at 356 pm est Mon jan 21 2019 high impact weather potential: active weather continues with several chances for accumulating snow through the weekend, along with another round of potentially very cold temperatures. An alberta clipper and associated arctic cold front move through late Thursday into Thursday evening with northwest flow lake effect to follow. The clipper front should bring a round of snow showers to the region. The lake effect behind it looks rather robust with decent moisture and gusty winds. This in combination with the very cold air (and low wind chills), visibilities will likely be lowered at times (small dendrites). This pattern is expected to continue into the weekend with periodic short waves moving through the flow enhancing activity. The one limitation may end up being the increasing ice cover on the big lakes. Temperatures will be upwards of 20 degrees below average. Highs on Friday will struggle to reach above zero once again. Aviation (for the 06z tafs through 06z Tuesday night) issued at 1145 pm est Mon jan 21 2019 strong arctic high pressure center will continue to slide east away from michigan overnight... As low pressure continues to develop to the lee of the rockies in the central plains. This system will gradually lift NE toward the great lakes region Tuesday and Tuesday. Widespread snow will develop ahead of the system and will impact all of michigan beginning on Tuesday and continuing Tuesday night and into Wednesday. Conditions will deteriorate to MVFR ifr as this widespread snow develops. Llws will develop as southerly flow strengthens ahead of this system tonight into early Tuesday. Marine Issued at 356 pm est Mon jan 21 2019 after some lighter winds today, widespread southerly advisory and possible gale producing winds return tonight into Tuesday, as the pressure gradient tightens between departing high pressure and developing low pressure in the central plains. The gradient will loosen up some and winds will decrease later Tuesday and Tuesday night as the low pressure lifts up into NRN michigan. Widespread snow is expected as this system passes.
