Short term (today through Tuesday)
issued at 435 am cdt Mon aug 26 2019
the forecast remains on track this morning, with widespread showers
and a few thunderstorms developing this morning out ahead of a
trough digging into the upper midwest. The only change tonight
was to slow the onset of precipitation by a few hours, as the cold
front is still out over the eastern dakotas and precipitation is
just now spreading into western minnesota. This precipitation
will continue to spread east through the day, beginning across
central southern minnesota by mid to late morning, eastern
minnesota and the twin cities metro by early afternoon, and west-
central wisconsin by mid-afternoon. Some thunder is currently
ongoing across western minnesota, but expect this threat to
diminish towards sunrise as instability weakens further east into
west- central minnesota. Mainly rain showers are expected with the
precipitation this morning, but we will likely see a few
thunderstorms redevelop this afternoon as MUCAPE increases above
500 j kg. Still looking like a widespread soaking rainfall, with
widespread rainfall amounts of around an inch expected for the
northern 2 3rds of the cwa. Locally higher amounts around 2 inches
are possible as well, but the rainfall looks to fall over a long
enough duration to mitigate much of the flooding potential.
Precipitation comes to an end from west to east this afternoon and
evening as the front clears the area to the east.
A breezy day is expected Tuesday as the surface low deepening to our
north and approaching high pressure from the west tightens the
pressure gradient over the region. Sustained westerly winds of 20-
25 mph are expected along with gusts of up to 30-35 mph. Cold-
advection behind the front will result in steep low-level lapse
rates tomorrow, which will kick off scattered diurnally-driven
showers across the northern half of the CWA as the wrap-around
region of the cyclone pivots over the upper midwest. Precipitation
amounts should be light, less than 0.1" total. Temperatures will be
cooler tomorrow and Tuesday, with cold advection and broken overcast
skies keeping highs in the mid 60s to low-70s.
Long term (Tuesday night through Sunday)
issued at 435 am cdt Mon aug 26 2019
canadian upper low will continue to deepen through Thursday as it
heads from northwest ontario to hudson bay. Trough axis exits the
area Tuesday night, with heights rising thereafter. Upper flow does
remain out of the northwest, however, keeping cool temps across the
area Wednesday. High temps will likely remain in the 60s over most|
areas on Wednesday. There is some indication a weak embedded wave
may graze northern mn and northwest wi late Tuesday night into
Wednesday, so precip chances will persist into Wednesday around
One more short wave enters british columbia Tuesday, and it tracks
toward northern minnesota on Thursday. Precip should stay well to
our north, while temperatures Thursday climb a good 10 degrees
warmer than Wednesday ahead of the wave. Most locales will be back
in the 75-80 range for highs, then drop back down on Friday to 68-72
or so after passage of the short wave. High temperatures next
weekend will be close to normal, in the low and middle 70s, as the
upper flow will be mostly from the west-northwest with no apparent
systems heading our way until perhaps Sunday night and Monday, which
is when ensemble members start diverging significantly.
Aviation (for the 06z tafs through 06z Monday night)
issued at 1159 pm cdt Sun aug 25 2019
should see a few MVFR ceilings develop and rain thunder move in
from the west overnight. Later today an area of rain will spread
across the region from the southwest, and should have clouds lower
as well. There is enough instability to mention thunder in the
tafs. Should see ceilings lift from west to east during the
evening as westerly winds increase.
did push back the timing of MVFR clouds one more hour to 11z since
the guidance seems to be a little to quick based on the current
trends. It still appears like the best chance for thunder will be
during the early afternoon. Should seeVFR conditions return
Monday evening as westerly winds increase.

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.
