Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 255 AM CST Fri Feb 28 2020

SHORT TERM.

Today through Saturday . Forecast confidence is high:

Still looks like a few flurries or light snow southwest of Madison early this morning as a weak waves slides through. Otherwise, quiet weather is expected through Saturday as high pressure slides by to the southwest.

Should see plenty of sunshine by afternoon. Bumped temps up just a tad based on highs from yesterday . though highs will still be around 10 degrees below normal. Clear skies and lighter winds will result in lows in the single digits most places, except for a little milder near Lake Michigan. Mostly sunny skies will continue into Saturday, with temperatures returning to near normal values.

LONG TERM.

Saturday night through Thursday - Confidence is Medium to High

Increasing southerly flow is expected over night as high pressure at the surface moves eastward and weak ridging shifts over WI. This will bring about a noticeable difference in lows Saturday night into Sunday with values about 20 to 25 degrees warmer. This warming trend continues into Sunday with highs in the upper 40s to lower 50s. One thing preventing temps from rising even further is an increase in clouds ahead of a weak cold front that drops south through the region Sunday night into Monday.

In terms of precip chances next week models continue to back off on the idea of strong southern stream system lifting far enough north to clip southern WI with precip. Guidance has on a whole shifted the overall track south and we may end up with just some light rain/snow Tuesday into Wednesday. While the trend is there will wait for another run before to see some consistency in this more southerly track before completely removing PoPs next week. Temperatures end up above normal with highs in the 40s and lows in the mid to upper 20s. This longer period of above normal temps will be perfect for melting the snow that is still around.

AVIATION(09Z TAFS).

May see a few flurries or some light snow southwest of Madison through early this morning. Otherwise, expect quiet weather through Saturday as high pressure slides by to the southwest. Ceilings may flirt with MVFR southwest this morning, with mostly clear skies then expected the rest of today through Saturday.

MARINE.

High pressure centered just north of Minnesota early this morning will slide southward today, reaching the MN/IA border by this evening. The high will then head south southeast to southern IL by Sat morning. Northwest winds will remain brisk today between the approaching high and low pressure well to the southeast. Though winds look borderline, will keep the Gale Warning going for northern Lake Michigan, as it still looks like gusts to 35 knots will be possible at times.

Winds will be lighter Saturday under more of an influence from the high. Winds will pick up a bit early next week, but gusts are expected to generally remain below 25 knots.

MKX WATCHES/WARNINGS/ADVISORIES. WI . None. LM . Gale Warning until 3 PM CST this afternoon for LMZ261-362-364- 563.

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.
