Short term (this evening through Thursday)
issued at 245 pm cst Wed jan 17 2018
little in the way of weather concerns in the short term.

The latest water vapor imagery is a rather vigorous short wave
moving through southern saskatchewan. Models still move this
system east southeast across northern mn toward the western great
lakes tonight and Thursday. Looks like we may work some mid high
level clouds across the northeast CWA during the period but it
still looks like it should remain dry.

South southwest low level flow to continue during the period and
will help temperatures warmer tonight with readings generally in
the teens. The warm start Thursday morning should allow readings
to warm through the lower 40s to the southwest and through the
30s elsewhere.

Long term (Thursday night through Wednesday)
issued at 245 pm cst Wed jan 17 2018
the main focus of the long term remains model
development movement of the western CONUS trough over the central
plains beginning this weekend.

Current water vapor imagery shows a potent trough over the
eastern pacific this afternoon. This feature comes ashore later
Friday and digs to the southwest over the southern rockies into
Saturday. Cyclogenesis occur late Saturday night or early Sunday
morning over the colorado oklahoma panhandle region and deepens as
it lifts northeast toward northeast iowa by Sunday evening. The
overall model trend has been to slow the system somewhat and
develop a closed circulation as it lifts east northeast. The
deterministic models have been trying to lift warmer air into the
southeast portion of the CWA as they have moved the surface low a
bit farther to the north. There, we could see a mixed
type rain sleet and or freezing rain into part of the south into
Sunday.

The main brunt of the storm moves through Sunday night through
Monday. If the system deepens like most models indicate at the
moment, heavy snow will be a definite possibility across southern
mn into western wi. Looking at the 12z probability plots of
greater than 6 inches of snow, the axis of the ensembles snow
band has lifted a little farther north, which would tend to favor
more of east central mn and west central wi. The GEFS plumes
continue to show a wide spread in forecast QPF snowfall and this
will likely continue until until the trough moves ashore Friday
evening.

We did follow the overall blended model guidance this run in the
pop as confidence increases with the storm system. We did
increase winds Sunday night into Monday night, with some gust at
least 35 mph. If the system deepens as depicted, we could see the
potential for significant blowing and drifting snow and possible
blizzard conditions over parts of the west.

Temperatures will warm through the 40s to the southwest leading up
to the system Sunday, and this should leave a decent crust in any
snow cover over the area. We will continue to monitor model
trends but it does appear southern mn and western wi will be
affected by this storm system by late in the weekend.

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.
