Area Forecast Discussion National Weather Service Duluth MN 529 PM CST Thu Feb 20 2020

SHORT TERM. (This evening through Friday night) Issued at 335 PM CST Thu Feb 20 2020

Mostly clear skies will continue across the Upper Midwest, as a strong area of high pressure continues moving south through the Great Plains. A dry warm front will move east through the region overnight, with southwesterly winds and warm air advection. Overnight low temperatures for Thursday into Friday will be chilly, with lows in the mid to upper single digits, and colder temperatures across northern Wisconsin.

Skies will remain mostly sunny on Friday, with continued dry air moving into the region. Breezy southwesterly winds with gusts of 20-25 kts are likely Friday afternoon, as winds at the 850 mb level mix down to the surface. Overnight, patchy fog is possible across the region as the warmer temperatures contribute to snowmelt and trap the released moisture under a strong inversion.

LONG TERM. (Saturday through Thursday) Issued at 335 PM CST Thu Feb 20 2020

The warming trend continues on Saturday with a surface high firmly planted over the central midwest. Aloft the low level jet will have moved out of the area bringing less windy conditions for the weekend compared to Friday. Surface winds will flow out of the west southwest. Aloft is ample dry air providing mostly sunny skies with temperatures climbing into the mid to upper 30s.

On Sunday another weather system coming off the front range of Colorado will bring snow and rain to much of the Midwest. However, the surface high pressure building out of the Dakotas will help steer this system to our south as well as the lack of a ridge downstream to give the system any further push north.

We will be on the lookout for some patchy fog or low stratus going into Saturday evening and into Sunday morning. The weak warm air advection we will be seeing throughout the weekend over our deep snowpack could give way to radiational fog. The NAM is heavily favoring this scenario with dewpoint depressions of less than 1 degree, but the GFS is starting to back off its initial assessment with values between 1-2 now.

Monday continues the zonal flow through the Northland. Overcast skies will also start building in late Sunday and into Monday within the mid and upper levels.

Going into Tuesday the weather pattern begins to switch once again with a meridional flow returning. An upper level trough begins to dig in through the Northern plains, which will usher in cold arctic air once again with temperatures steadily dropping Tuesday through Thursday. Wrap around moisture from the exiting low that impacted the central midwest will also bring the chance of flurries Tuesday through Thursday.

AVIATION. (For the 00Z TAFS through 00Z Friday evening) Issued at 526 PM CST Thu Feb 20 2020

Clear skies across the region with a warm front crossing tonight. Models indicate that there may be a thin layer of saturation, so will have to watch for low cloud development, but given the fact that there is nothing currently out there on satellite imagery - opted to keep out of TAF. LLWS will be prevalent as strong winds move in aloft of a strong, but shallow, temperature inversion. Winds above the inversion will peak near 50 knots from the west around daybreak on Friday.

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.
