Marine Weather and Tides
Version 3.4 |
10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 523 AM CST Sun Dec 15 2019
UPDATE. No updates to the previous discussion.
AVIATION(12Z TAFS). VFR conditions are expected through the forecast period with northwest winds decreasing through the day. Clouds will increase tonight with ceilings around 5,000 to 8,000 feet late tonight. Areas along the WI/IL border may briefly see MVFR ceilings between 06-10Z Monday.
PREV DISCUSSION. (Issued 336 AM CST Sun Dec 15 2019)
SHORT TERM .
Today through Monday . Forecast Confidence is High . Quiet conditions are expected for today and tomorrow as high pressure sits over the area. Mostly sunny skies will give way to more clouds tonight as a low pressure system passes to the south. The dry air associated with the high pressure is expected to keep precipitation south of the area, but flurries can't be completely ruled out along the state line as 850mb convergence may briefly overcome the dry air. Clouds will linger into Monday, but temperatures will be warmer with highs in the mid 20s to low 30s.
Monday night through Tuesday night . Forecast confidence high.
A large upper low and associated sfc low will track from south central Canada to New England during this period. The sfc low will gradually deepen as it does so. Ahead of this feature, a west to east sfc ridge will shift south across srn WI Mon nt-Tue AM. Modest wly winds will prevail on Tue shifting nwly for Tue nt with a dry cold frontal passage. A cold night, mostly in the single digits, is forecast for Tue nt.
LONG TERM . Wednesday through Saturday . Forecast confidence medium.
Will continue to use the ECMWF and NBM as guidance in the extended fcst. Polar high pressure will arrive for Wed with a cold day expected. Milder temps are then expected the remainder of the week as sly flow and warm advection develops ahead of an approaching shortwave trough from the wrn USA. A weak cold frontal passage will eventually occur on Sat. The airmass may remain dry enough for no precipitation.
AVIATION(06Z TAFS) .
MVFR ceilings are clearing this morning with VFR conditions expected for the remainder of the day. Winds will be from the northwest and decrease through the day becoming light and variable this evening. Clouds will move back in from the south tonight with ceilings around 7,000 to 10,000 feet.
MARINE . Northwest winds will decrease today as high pressure builds in. Light winds will then continue until Tuesday as deepening low pressure system develops over southern Ontario. Winds will increase from the northwest through Tuesday with gusts up to 30 knots Tuesday night into Wednesday morning. A Small Craft Advisory may be needed for the nearshore waters Tuesday night.

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. |
