Aviation(12z tafs)

to mid afternoon.

discussion...

today and tonight... Forecast confidence is high.

The high pressure weather pattern remains locked in. 925mb temps
have cooled ever so slightly, so although temps may be a few
degrees cooler than yesterday, it will still be hot. We could see
another round of record highs achieved. Madison's record is 90 and
the forecast is 91. Milwaukee's record is 93, but the forecast is
around 90. Skies will remain mostly clear through tonight.

Sunday and Monday - confidence... Medium to high
the unseasonable warmth will persist ahead of an approaching
frontal boundary. The 12z ECMWF was bringing some precip in Monday
afternoon though the 00z run has backed off on this so expecting
much of the area being dry with some small chances in the far
west. Much of the are likely to remain dry Monday night as well.

The other models were holding things off until Monday night with
the better dynamics and low level convergence with the low
staying to our west. 925 temps both days will be in the low mid
20s celsius so the highs should get be well into the 80s once
again.

Tuesday - confidence... Medium
enough energy breaks down the mid level ridge with surface low
and frontal boundary helping to trigger off chances of shra isold
tsra. The progs suggest the chance would linger into Tuesday
evening. The ECMWF is showing the fastest solution with a quicker
end time to rain chances.

Wednesday - confidence... Medium
the low and associated cold front are proggd to shift off to the
east with high pressure taking hold. 925 temps drop off into the
teens celsius so a cooler and less humid airmass pushes in.

Thursday and Friday - confidence... Medium
the pattern will be more fall-like with a pronounced northwest
flow aloft bringing in a more energetic regime. The most
pronounced trough arrives later Thursday night into at least part
of Friday. So will have shower chances both days. Both the GFS and
ecmwf show Friday as the coolest day with 925 temps down to single
digits celsius. So may see highs not getting too far above 60.

Aviation(06z tafs)...VFR conditions will persist through the taf
period. A lake breeze with southeast winds will kick in at kmke
around mid day and a few hours later at kues kenw.

Marine... Winds and waves will remain below small craft advisory
levels into early next week. Be ALERT for areas of fog, especially
north of port washington over the next few days. The very warm
and moist airmass will combine with the cooler waters of lake
michigan to help generate the fog from time to time.

Mkx watches warnings advisories
Wi... None.

Lm... None.

Update... Davis
today tonight and aviation marine... Davis
Sunday through Friday... Collar

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.
