forecast discussion for routine morning forecast issuance

Short term Today... Tonight... And Monday
issued at 310 am cdt Sun sep 24 2017
above normal temperatures will continue today into Monday. The
primary forecast challenge centers on precipitation chances for
Monday.

Southwest flow aloft and southerly surface winds ahead of a
northern plains frontal system will produce similar temperatures
today compared to the last couple of days. This means many
locations will reach or just exceed the 90 degree mark for the
third day in a row.

Progs in good agreement with the frontal system and precipitation
chances slowly drifting into the state on Monday, reaching parts
of central and north central wisconsin. The eastern part of the
state is expected to remain dry and very warm with maximum
temperatures reaching the mid 80s at least.

Long term Monday night through Saturday
issued at 310 am cdt Sun sep 24 2017
500mb ridge responsible for the unseaonably warm hot and humid
weather will gradually flatten early this week. The pattern will
shift to a west northwest flow as ridge builds across the rockies.

The warm spell will come to an end Tuesday as a cold front moves
across the state. The front will bring a chance of showers and
thundertorms. At this time, some of the storms could bring gusty
winds and locally heavy rain. At this time, the risk of severe
weather is low.

A few showers may linger past midnight Tuesday night, and across
the far north into Wednesday morning. High pressure will dominate
the weather pattern Wednesday afternoon into Thursday morning. The
next cold will drop southeast into the northern united states
Thursday afternoon. The front will bring a chance of showers to
much of the area Thursday afternoon or Thursday night. Latest
numerical guidance has backed off on the cool air for next
Friday and Saturday. However, will continue with our cooler
forecast for now since mex guidance values are greatly influenced
by climatology in the later periods. Usually, large canadian high
pressure systems this time of year are usually capable of
producing lows in the 30s, especially across the north.

Aviation For 06z TAF issuance
issued at 1036 pm cdt Sat sep 23 2017
mainlyVFR conditions to persist over the next 24 hours, other
than some patchy late night fog which could lower vsbys into the
MVFR range. Given the high cirrus currently in place from upstream
thunderstorms the threat from fog does not appear to be that high.

Some llws is possible at krhi later tonight as winds just above
the surface could reach 30 knots. Llws will dissipate with mixing
Sunday morning, however it will return during Sunday evening
across the western TAF sites as low level winds once again
increase to around 30 knots.

Grb watches warnings advisories
None.

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.
