Forecast discussion for routine afternoon forecast issuance
SYNOPSIS. Issued at 231 PM CST Mon Dec 9 2019
Wintry precipitation ending this evening, then a brief shot of much colder air for the middle of the week. Temperatures returning to above normal by the end of the work week.
The amplitude of the large scale flow across the CONUS has peaked. A strong jet surging east from the Pacific will rapidly undercut West Coast ridging, transitioning the flow across the CONUS into a seasonably strong highly zonal regime by late in the week. Some reamplification now seems likely late in the period, with a trough forming over the Rockies and ridging developing near the West Coast and from the Gulf of Mexico into the Atlantic.
Much colder air surging into the area will take temperatures briefly down to considerably below normal by mid-week, but readings will rebound to above normal by the end of the work week and the start of the upcoming weekend before falling off again at the end of the period. Though the details of individual systems that will affect the area remain sketchy given the developing zonal flow, there will likely be at least a couple rounds of precipitation during the period. But with Gulf moisture likely remaining south and east of the area, amounts will probably end up below normal.
SHORT TERM. Tonight and Tuesday Issued at 231 PM CST Mon Dec 9 2019
Drizzle, freezing drizzle and snow continued across the region this afternoon. Temperatures ranged from near 20 across the far north to the middle 30s at Manitowoc.
A band of heavy snow continues to move across northeast Wisconsin this afternoon. Issued a winter weather advisory earlier for the Fox Valley and lakeshore as this heavy band of snow will impact the afternoon and evening rush hours. Visibilities in this band of snow were down to around a quarter of a mile. With poor visibilities, falling temperatures and roads becoming snow covered will make for hazardous conditions. For the locations north and west of the Fox Valley, current ending of headlines looks good. Light snow will linger into Tuesday morning across the far north although accumulations will be on the light side.
Colder air works in the region tonight with lows in the single digits below zero across north-central Wisconsin with readings near 10 above across the Fox Valley and lakeshore. Snow showers will linger across the far north tuesday, otherwise it will be partly cloudy and cold with highs in the single digits well west and north of the Fox Valley to the teens across the Fox Valley and lakeshore.
LONG TERM. Tuesday Night Through Monday Issued at 231 PM CST Mon Dec 9 2019
The most significant combination of cold temperatures and wind still looks like it will occur late Tuesday night through Wednesday morning. The forecast apparent temperature has eased a bit from what it was a couple days ago, but would support a Wind Chill Advisory across about the northwest half of the area. That's still over a day away, so will allow the current headlines to continue to play out and forego posting the advisory with this forecast issuance.
Temperatures Wednesday night into Thursday are much trickier. Clouds will eventually increase from the west, but that may not occur until after dark. Winds will be very light or calm with the anticyclone center sprawled across the region. It's quite possible that temperatures will plunge rapidly during the evening, then bounce back once clouds move overhead. Of course, the timing of the arrival of the clouds will be critical and might still change with later forecasts. For now, adjusted temperatures downward several degrees and amplified the atypical diurnal temperature trend in the hourly temperature grids.
Ascent due to isentropic lift along the back side of the receding cold air mass combined with weak/ill defined shortwaves crossing the region in the developing zonal flow regime will likely bring a couple rounds of light snow in the Thursday-Saturday time frame. Thursday, and Friday night into Saturday look like the most favorable times at this point. But the low amplitude nature of the flow typically leads to timing difficulties, so precipitation timing could change in later forecasts. Regardless of the timing, an inch or two of snow will be possible with each event.
AVIATION. for 18Z TAF Issuance Issued at 1153 AM CST Mon Dec 9 2019
Drizzle and freezing drizzle will switch over to snow this afternoon from west to east. A band of moderate to heavy snow will sweep across the area along and just behind the cold front with IFR and lower conditions. The precipitation should gradually end from west to east across much of the area late this afternoon and evening, except across the far north where snow showers will linger into Tuesday morning. Gusty northwest winds to near 30 knots are possible across much of the area this afternoon into early this evening, then gradually diminish overnight. CIGS expected to rise into the MVFR/VFR category tonight. Winds back to the west on Tuesday.
GRB WATCHES/WARNINGS/ADVISORIES. Winter Weather Advisory until 8 PM CST this evening for WIZ022- 038>040-048>050.
Winter Weather Advisory until 6 PM CST this evening for WIZ005- 010>013-018>021-030-031-035>037-045-073-074.
