Short term (this evening through Monday)
issued at 250 pm cdt Sun jul 22 2018
another pleasant day today with early morning stratus burning off
into cumulus, dew points in the low 60s, light winds, and
temperatures in the mid 70s to lower 80s. Increasing moisture in
the central and northern plains however is expected to result in
evening and overnight convection over the dakotas. This will
weaken to perhaps just a few showers by the time it reaches west
central central mn late tonight due to very limited instability.
Maintained chance pops, but reduced the thunder mention. Cams are
not too optimistic for more than a few showers either.
The cold front will be pushing through in the morning. Some
instability will build near and ahead of it by early afternoon and
some thunderstorms could develop along and east of i-35.
Convergence will be very weak, and the lack of focus will be a
detriment to more widespread activity. Did increase pops 10 to 20
percent from the previous forecast, but they remain about 40
percent or less.
Long term (Monday night through Sunday)
issued at 250 pm cdt Sun jul 22 2018
past Monday night, the best chance of widespread rainfall will occur
Wednesday Wednesday night as a stronger frontal boundary, and
associated short wave, moves across the upper midwest. Once this
front passes, the onset of much cooler temperatures develop with
readings averaging 5 to 10 degrees below normal for late july.
Models have been consistent with this stronger cold front on
Wednesday, but slight timing differences were noted with the ec
slower than the operational gfs, or the parallel gfs. However, even
with timing differences, the stronger short wave will allow for
better upper level dynamics, and the potential of widespread one
quarter to one half inch of rainfall.
As the main storm system begins to sagged southward into the great
lakes region by late in the week, I wouldn't be surprised to see a
few instability showers as the core of the cold air rotates
southward Thursday or Friday.|
There will be a brief moderating in temperatures next weekend as the
core of the coldest air moves southward. However, the mean upper
pattern is conducive for another surge of abnormally cold air
arriving the last week of july, and into early august. Although it
doesn't appear to be record cold, forecast dew points the week of
july 30th lowers into the 30s 40s in northern minnesota, with
40s 50s in southern minnesota.
Overall, there is a high probability of cooler than normal
temperatures after Wednesday, with lower chances of rainfall and
more comfortable humidity levels.
Aviation (for the 00z tafs through 00z Monday evening)
issued at 654 pm cdt Sun jul 22 2018
thunderstorms forming along a cold front in the dakotas are
expected to encounter a hostile environment over mn as we sit in
an area of subsidence to the west of the expansive upper low
across the lower great lakes and ohio valley. As a result, have
kept tafs dry, save for a vcsh mention out at axn. The hrrr and
hopwrf are not very promising for seeing much precip locally with
the fropa, so continue the theme of dry tafs. Behind the front,
there could be a brief period of MVFR CIGS across central mn, but
confidence in seeing CIGS that low this far south is low enough
whereVFR conditions were maintained at all terminals.
Kmsp... Can't completely rule out a stray shra tsra between 16z and
20z, but chances for seeing anything are too low to include in the
taf at this point.
Outlook for kmsp
tue...VFR. Wind NW 5-10 kts.
Wed... Chc MVFR -shra -tsra. Wind W bcmg NW 10g20 kts.
Thu... Chc MVFR cigs. Wind NW 10g20 kts.

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.
