Short term
Tonight and Friday - confidence... Medium to high
the main story will continue to be the unseasonable heat and
humidity. The return flow around the departing high will setup
overnight and pick up even further on Friday. The 500 millibar
heights will gradually build up as well within the broadly
anticyclonic southwest mid level flow. The southerly flow will
reinforce 925 temps in the mid 20s celsius. So expecting near
record high minimums tonight with some record highs in jeopardy
for Friday with highs pushing to near 90.

Friday night through Monday... Forecast confidence high.

A strong upper ridge from the central usa to the ERN great lakes
will move slowly to the mid atlantic states during this period.

At the sfc, high pressure will remain centered over the ERN great
lakes and mid atlantic states with a n-s sfc trough cold front
from the SRN great plains to NE mn or NW wi. A light sly flow will
prevail over SRN wi with continued very warm and humid conditions.

Record high temps are possible inland for sat-sun while a lake mi
lake breeze is expected each afternoon.

Long term Tuesday through Thursday... Forecast confidence
medium.

An upper trough lifting newd from the WRN usa may induce
cyclogenesis along over ontario, canada. This would drive a cold
front through SRN wi either Tue or Wed with chances of showers or
storms. High temps should cool into the upper 60s for wed-thu.

Aviation(18z tafs) OverallVFR period expected as return flow
sets up. Looks like enough wind off the deck to keep widespread
fog at bay. But some patchy fog not out of the question. Some
concern for llws across parts of sc wi as the low level flow
strengthens above the inversion. Surface sse flow picks up for
Friday with little cloud cover and building 500 millibar heights.

Marine Winds will be on the light side right into the upcoming
weekend, with low waves expected as a result.

Mkx watches warnings advisories
Wi... None.

Lm... None.

Tonight Friday and aviation marine... Collar
Friday night through Thursday... Gehring

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
