Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 521 AM CST Sun Jan 19 2020

UPDATE. No change to forecast at this time.

PC

AVIATION(12Z TAFS). MVFR stratocu expected to continue pivoting through the area in cyclonic flow. Pressure gradient expected to slacken some today with more relaxing overnight. West/northwest winds will become more northwest with time today and then ease some overnight with a more slack pressure gradient.

PC

PREV DISCUSSION. (Issued 343 AM CST Sun Jan 19 2020)

SHORT TERM .

Today and Tonight - Confidence . Medium

Bitter cold westerly flow keeping wind chills near -20F for parts of the advisory area. Stratocu within the dendritic growth zone resulting in flurries. We will see some 925 waa today from the north. Overall low/mid level cyclonic flow will keep the stratocu around so will keep flurry mention into tonight. Will have to keep an eye on cloud trends into tonight as any appreciable breaks here and there could result in temps dropping lower than forecast given an overall lighter wind regime.

Monday through Tuesday night . Forecast confidence high.

A fairly robust shortwave trough will track from the ern Dakotas early Mon to the se USA by 12Z Tue. The snow is expected to remain to the west on Mon with some mid to upper level clouds over the area. The clouds will decrease during the late morning and early afternoon. Upper ridging will follow the shortwave trough through Tue, while the arctic high tracks from the Dakotas to the middle MS River Valley and then ewd across the Ohio River Valley. This will allow swly winds and warm advection to begin on Tue. Temps will remain a few degrees or so below normal for this period.

LONG TERM . Wednesday through Saturday . Forecast confidence medium.

For this period, an upper trough will dig sewd from sw Canada or the Pacific NW. There is wide model spread on digging anywhere across the Rockies to the Great Plains with cyclogenesis eventually occurring. Either way, shortwave troughs within the swly flow aloft will bring a return of relatively mild and moist air along with chances of snow and possibly rain at times.

AVIATION(09Z TAFS) . MVFR stratocu expected to continue pivoting through the area in cyclonic flow. Pressure gradient expected to slacken some today with more relaxing overnight. West/northwest winds will become more northwest with time today and then ease some overnight with a more slack pressure gradient.

MARINE . Tight pressure gradient keeping open lakes gale/freezing spray headlines in good shape at this time. Will convert the nearshore gale to a small craft at 09z.

MKX WATCHES/WARNINGS/ADVISORIES. WI . Wind Chill Advisory until noon CST today for WIZ056-057-062>064- 067>070.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
