Short term (this evening through Monday)
issued at 320 pm cst Sun feb 17 2019
light snow has shown signs of diminishing across the area this
afternoon, but the expectation is that light snow or flurries will
linger at least through the early night time hours as a vort tail
behind the exiting upper level low pulls across the region.
Additional accumulations will generally be a half an inch or less.
Colder air will begin to filter in behind the exiting system, so
temperatures will be a little cooler tonight - dropping mainly
into the single digits.
Canadian high pressure builds into the region on Monday, keeping
cold temperatures across the area. Highs will be in the teens.
Long term (Monday night through Sunday)
issued at 320 pm cst Sun feb 17 2019
the active weather pattern continues on Tuesday as another upper
level trough tracks into the northern plains. There are still some
differences among the models with regard to both upper and surface
level features, though there is a fairly good consensus on the
potential for moderate snow accumulations over our area for Tuesday
afternoon into Wednesday afternoon. As in the recent event, winds
look to be relatively light so blowing snow should not be an issue.
Although there will be some gradual moderation in temperatures for
the remainder of the week, readings still look to be below normal
for this time of year. And once again, snow looks to move back into|
the area for Thursday night through Friday. Although there are model
differences, there will be another potential for light to moderate
snowfall accumulation across the area.
Aviation (for the 00z tafs through 00z Monday evening)
issued at 527 pm cst Sun feb 17 2019
periodic light snows will continue into the overnight hours.
Ceilings will vary considerably through the night, ranging from
lowVFR to high ifr in a few spots. Visibility may temporarily
drop near 1 mile at times, but should prevail around 3 to 4 miles
in most locations.
Ceilings may slowly improve through the day on Monday.

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.
