Woodland, MN

Version 3.4
What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Short term (today and tonight)
issued at 356 am cdt Mon mar 19 2018
the short term concern remains the timing of incoming trough and
attendant snow and amounts.

Clouds have been persistent but there have been sporadic holes in
the lower clouds, especially to the east. This trend may continue
into the morning mainly to the east as the easterly lower level
flow tries to draw in some drier air from the canadian high. This
will influence overall movement of the western trough into the
area and should limit any significant precipitation over the
eastern cwa. Temperatures are expected to warm into the lower 40s
to the east today, with mainly the mid upper 30s to the west.

We presently increase the snow chances into far west central mn by
00z tue. This precipitation area will move into western CWA during
the evening with categorical pops indicated as the upper
trough surface inverted trough move in. Forcing remains rather
weak with the trough and will slowly work into eastern mn by 12z
tue. Currently we have around 2 inches accumulating over west
central mn by 12z Tue with less than an inch toward the west

Long term (Tuesday through Sunday)
issued at 356 am cdt Mon mar 19 2018
Tuesday through Thursday... While the aforementioned low pressure
system through the short term portion of the forecast shifts to
the southeastern conus, a lingering surface trough from this
system extending into the upper mississippi river valley will be
responsible for continued light snow (with possibly some light
rain mixed in at times) for much of the day on Tuesday and mainly
for the mn portion of the WFO mpx coverage area. The snow looks to
wind down late Tuesday through Tuesday evening, resulting in
potentially up to an additional inch of snow accumulation, most of
which will be seen in western mn. High pressure oriented nearly
n-s over the central portion of the CONUS will then prevail across
mn wi for Wednesday-Thursday. In conjunction with the surface high
pressure, an upper level ridge which had been building over the
western CONUS over the early portion of this week will shift into
the central states. The combination of the surface high with
increasing heights aloft will produce mainly clear skies and mild
temperatures. While highs only remain in the lower 30s on Tuesday,
highs will jump to the mid 40s by Thursday.

Friday through Sunday... This portion of the forecast still remains
rather murky due to poor model agreement and fairly wide swings in
temperatures throughout the duration of what looks to be a
prolonged rain snow event. A potent upper level low will move into
the pacific northwest during the day on Friday with its trough
opening up over the rockies during the day on Saturday. A smaller
piece of energy out of this trough will eject into the central
plains Friday night, helping kick a compact low pressure center
from western ks into the ohio valley Friday night through Saturday
afternoon. A mixture of pacific and gulf moisture in advance of
this system will be quickly tapped to produce 0.50"-1.0-" of qpf
across the WFO mpx coverage area. The bulk of this QPF looks to
come as rain Friday into Friday evening then change over to snow
as the system shifts slides off to the east Friday night into
Saturday morning. After a break in the action Saturday night, the
remainder of the western trough will shift into the central conus
in a weakened state and produce additional rain snow showers
Sunday into Monday. This portion of the event looks to be more
disorganized than the Friday portion, so while pops are in the
likely to categorical ranges for Friday, pops are capped in the
chance ranges for Sunday. Because temperatures will range from the
lower 20s to lower 40s throughout this portion of the forecast,
confidence is low on any kind of snowfall amount at this point.

Aviation (for the 06z tafs through 06z Monday night)
issued at 1019 pm cdt Sun mar 18 2018
cigs will bounce around tonight through Monday between 2500 and
4000 feet, so we will be in and out of MVFR cigs. Rap still shows
considerable low level drying occurring through Monday as
northeast winds becomes established, helping to raise the cigs.

For precip, followed timing of the nam, which is much slower than
the gfs. With the dry northeast winds, slower is better when it
comes to timing for snow moving in. Axn will likely see by the end
of it's taf, with rwf, stc, and msp having precip on their
doorsteps by the end of each TAF period.

Kmsp... Rap and NAM say msp will see moreVFR CIGS than MVFR.

Played CIGS to prevailVFR, but left the idea of periods of MVFR
cigs happening with the sct025 cloud grouping seen throughout.

Snow will likely be close to msp by 12z Tuesday, but snow chances
look better after 12z, so kept snow out of the 06z msp taf.

Outlook for kmsp
tue... MVFR CIGS likely. Chc ifr with -sn. Wind E 5 kts.

Wed... MVFR CIGS possible. Wind E 5 kts.

Thu...VFR. Wind SE 5 kts.

Mpx watches warnings advisories
Wi... None.

Mn... None.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
