NEAR TERM. (Today through Tonight) Issued at 230 AM EST Sat Feb 27 2021
. Mild temperatures to kick off the weekend .
High impact weather potential: A bit of light snow early this morning. Minimal accumulations and impacts expected.
Pattern synopsis and forecast:
Broad troughing encompassing much of western and central Canada down into the northern Rockies and northern Plains early this morning, with broad ridging extending the entirety of the eastern seaboard. Weak shortwave trough rotating northeast across the lower lakes in deep southwest flow between these features. System is a relatively moisture starved one, but just enough forcing/moisture to kick off a bit of light rain and snow across the central and lower lakes. Some of this light snow just now pushing into our southern areas, with minimal accumulations and impacts. Plenty of high and mid level clouds otherwise, and when combined with southerly low level flow, is resulting in a seasonably mild night across the Northwoods, with current readings mostly in the lower and middle 30s.
Shortwave trough will continue to rotate northeast across lower Michigan early this morning, exiting stage right by later this morning/early afternoon. Additional shortwave energy digging into the Rockies and out into the central Plains will help build mid and upper level heights across the northern Lakes tonight.
Primary forecast concerns/challenges:
Addressing light snow this morning. Temperature and cloud trends through the near term.
Details:
Passing shortwave and attendant plume of steeper mid level lapse rates early this morning will swing an area of light precipitation across the area. Guidance derived sounding show this precipitation falling as light snow, with snow accumulations likely remaining under an inch ("heaviest" totals southeast half of the area). Expect snow to steadily end from southwest to northeast, resulting in dry conditions rapidly developing after sunrise (if not before). Post- system environment is definitely not cold enough for the development of any lake processes, and given rapid loss of moisture through the column, gotta believe most areas will see some sunshine this afternoon, especially so south of the big bridge. This will result in another relatively mild end of February day, with afternoon temperatures ranging from the upper 30s to middle 40s . several degrees above normal for this time of year.
Ridging will dominate our weather tonight, with trends supporting any impacts from that next upstream wave holding off until after sunrise Sunday (other than some increasing clouds with time). Another fairly mild night, with lows mostly in the middle and upper 20s.
SHORT TERM. (Sunday through Monday) Issued at 230 AM EST Sat Feb 27 2021
. Same Drizzle, Different Day .
High Impact Weather Potential . Freezing drizzle is possible on Sunday, impacting roadways. Accumulating snow Monday.
Pattern Synopsis/Forecast and possible impacts . Sunday, the last two nights the models showed that the low level moisture would increase during the morning, before the mid-level moisture, and produce drizzle, and with the sfc temperatures below freezing, freezing drizzle would result. However tonight's GFS shows the moisture and precipitation not getting into the forecast area, until after 15z when temperatures will be above freezing. This meshes with the 00z/ECMWF as well. So it looks like it would be dry before 15z/Sun and then after the temperatures rise to well above freezing, the precipitation will fall as rain. Sunday night, the system moves out, and there will probably be a short break before the 850 mb temperatures fall late Sunday night/Monday morning so that lake effect snow starts. Monday, a 500 mb shortwave trough moves through the region, and coupled with the -15c and cooling 850 mb temperatures lake effect/enhanced snow will be falling, with some bands expected to be significant. Monday afternoon will probably see the snow diminishing, but not stopping until sometime in the evening or even overnight. 850 mb temperatures warm to above -10c by 12z/Tue, so the instability with the lakes should be on the wane.
LONG TERM. (Monday night through Friday) Issued at 230 AM EST Sat Feb 27 2021
High Impact Weather Potential . Minimal.
Extended (Tuesday through Friday) . Tuesday and Wednesday look dry, as the upper and sfc ridges are over the region. Thursday will probably be dry as well, but there is some cyclogenesis north of the ANJ, as the baroclinic zone sharpens up. However, the moisture in is pretty sparse, especially in the 700-500 mb layer. The ECMWF no longer has the cut off low at 500 mb, and has the region dry as well. Friday, looks like it cloud also be dry as the ridge in the Plains leans over into the Upper Great Lakes. The ECMWF does push a shortwave through Friday evening, which could bring something, but based on the trends of the ECMWF the last few nights, think this may go away and look like the GFS.
AVIATION. (For the 06Z TAFS through 06Z Saturday night) Issued at 1151 PM EST Fri Feb 26 2021
Spotty -SHSN overnight. LLWS ending at TVC/MBL/PLN overnight.
An upper-level disturbance will bring sct -SHSN into MI late tonight. The most widespread precip will be in central/southern lower MI. mbL/APN are the most likely spots to see -SHSN and associated brief vsby restrictions. APN is likely to see a period of MVFR cigs Sat morning. Otherwise, mainly VFR, and the risk for -DZ/-FZDZ looks less than earlier expected.
Southerly winds tonight will be a bit brisk, becoming sw and w on Saturday. LLWS at TVC/MBL/PLN ending before daybreak.
MARINE. Issued at 230 AM EST Sat Feb 27 2021
No significant marine impacts to start the weekend as a weak pressure spreads overhead. Steadily deepening low pressure expected to cut across upper Michigan on Sunday will likely bring the return of small craft advisory conditions, especially during the afternoon and evening when winds become gusty out of the northwest.
