Short term (this evening through Sunday)
issued at 307 pm cdt Sat aug 24 2019
at 2 pm, surface high pressure continues exert its influence on
the upper midwest this afternoon with dry low-level easterly flow
and seasonable temps. Temperatures were around 70 north of
interstate 94 and in the lower to mid 70s elsewhere. The
diurnally generated CU field will dissipate by early this evening.
The high will continue to work slowly east into Sunday ahead of a
mid-level trough moving into the central plains and a stronger
trough upper jet working across the northern rockies. Moisture will
gradually increase as low-level flow fields slowly shift southerly.
The increasing flow, especially off the surface tonight, will keep
valley fog at bay, although a bit may develop along a few of the
tribs wi river valley. The warm moist advection will lead to
increasing mid high clouds into Sunday. Kept a dry forecast through
the day, despite a few models hinting at scattered showers trying to
spread north into NE ia SW wi ahead of the trough lifting northeast
from the central plains into mo ia by the afternoon. Some modest
isentropic ascent will develop, but much of the moisture increase
looks to be in the mid-levels, as the low-level moisture transport
remains focused to the west through the day. With plenty of dry air
to be overcome, confidence in any precip reaching the ground is low.
Winds will be a bit breezier from the SE with highs in the 70s.
Long term (Sunday night through Saturday)

on Sunday night, a short wave trough will eject out of the central
plains. Like the past couple of days, this system will be moving
into a rather dry airmass. Due to this, confidence is not overly
high that we will see any showers and storms from this system. As
a result, rain chances remain in the 20 to 30 percent range.
On Monday and Monday night, a canadian cold front will move east
and southeast through the region. The models continue to struggle
on the tilt of the upper wave. The GFS continues to suggest a more|
negatively tilted system. This results in more deep (0-6 km) shear
south of interstate 90. Also a bit more instability (most unstable
capes of 1-2k). Meanwhile, the nam, canadian, and ECMWF has more
of a neutral tilted wave which keeps the deep shear either on or
in the wake of the front. This also results in far less
instability. At this time, thinking that the GFS may be an
outlier, so thinking that we will not see much severe weather from
With precipitable water values around 1.7 inches and strong
frontogenetic forcing, there will be the potential for some heavy
rain from Monday afternoon into Monday evening. Rainfall amounts
will likely be in the half to 1 inch range with locally higher
Small shower chances will be possible mainly north of the area
Tuesday night and perhaps Wednesday as that area remains under the
influence of 500 mb trough over ontario. As this feature moves off
to our east Wednesday, surface ridging tries to build in for
midweek. Details get a little murky beyond Wednesday, with latest
model runs beginning to show a potential front moving through the
area for late week which could be accompanied by small
precipitation chances, but this far out confidence is low.
Temperatures still look near to slightly below normal for this
period, but potential is there for a sneaky warmer day if things
are able to warm up ahead of any late week front.

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.
