Short term (today and tonight)
issued at 316 am cdt Thu mar 21 2019
as subsidence and dry air move into the area, the clouds will
continue gradually decrease from the west and northwest this
morning.

For this afternoon and evening, a canadian cold front will push
south through the area. Other than an increase of clouds mainly
across wisconsin and a drop in 925 mb temperatures by 3 to 5c,
there will be little weather associated with this front.

High temperatures will range from the mid-40s to mid-50s this
afternoon. Low temperatures on Friday morning will be mainly in
the 20s.

Long term (Friday through Wednesday)
issued at 316 am cdt Thu mar 21 2019
on Friday, 925 mb temperatures will range from -3c and +1.5c
during the afternoon. The coldest temperatures aloft will be
found north of interstate 94. High temperatures there will range
from the mid-30s to mid-40s. Elsewhere, they will be in the 40s.

On Friday night, the upper level ridge will slide across the area.

As this occurs, the winds will become more southerly and warmer
air will be advected into the region. However, it will likely not
be as warm as we originally expected. High temperatures on
Saturday will likely only range from the upper 40s to mid-50s.

From late Saturday night into Sunday night, a low pressure system
will move south of the region and a canadian cold front will move
south through the region. The models are still struggling on the
placement of the precipitation. At this time, the highest rain
chances look to be south of interstate 90. As colder moves into
the region on Sunday night, whatever precipitation is left will
likely end as snow. Rainfall amounts look to be up to a quarter
inch. Snow amounts will likely be just a dusting.

In the wake of this system, much colder air will move into the
region for Monday. 925 mb temperatures will range from -3c to -8c.

This will result in high temperatures ranging from the mid-30s to
lower 40s.

From Tuesday into Wednesday, the temperatures will gradually warm
as an upper level ridge builds across the region. By Wednesday,
high temperatures will likely range from the upper 40s to mid-50s.

Aviation (for the 12z tafs through 12z Friday morning)
issued at 619 am cdt Thu mar 21 2019
mfvrVFR strato-cu deck from the evening has been dissipating and
advecting east of the TAF sites thru the overnight hours. GoodVFR
expected today as high pressure and a deep, dry airmass from the
northern plains and canada spreads into the region. Around 20kts of
wind at the top of the mixed layer this afternoon, for some gusty nw
winds at time during the afternoon peak diurnal heating. This
diminishes rather quickly by or around 00z, however a mdt pressure
gradient to remain over the area tonight as another cold front moves
south across the area. NW winds around 10kts to continue much of
tonight.

Hydrology
Issued at 316 am cdt Thu mar 21 2019
minor flooding continues along the black and trempealeau, but the
stages are falling for the most part as runoff from last week
continues to drain into the main stem of the mississippi river.

Minor flooding continues at mcgregor and guttenberg along the
mississippi river. Additional areas will likely see flooding next
week as snow melt runoff from more upstream tributaries like the
chippewa, st. Croix and minnesota rivers begins to reach our
area.

Ice jams remain possible in the tributaries. There was one reported
along the black river in southern clark county late last evening.

However, this threat is diminishing as increased flow breaks up
the remaining ice.

With temperatures not quite as warm at the end of the week, the
magnitude of river flooding looks less on the mississippi tributaries
for the weekend. In addition, it could potentially delay the time
of arrival of the flood wave coming down the mississippi river.

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.
