10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

SHORT TERM. (This evening through Tuesday) Issued at 220 PM CST Mon Dec 9 2019
As this system continues to move out, lingering light snow showers will continue to move east and out of the region by tonight. Cold air advects in behind the cold front and high pressure builds into the region. Gusty northwesterly winds will diminish into the teens overnight and last through tomorrow afternoon. Temperatures combined with wind will create wind chills into the -10 to -20 range by Tuesday morning.
After midnight, there is a chance for flurries through tomorrow afternoon. The further north and east into Wisconsin, the greater the chance for flurries as soundings show decent lapse rates and better low level saturation than areas to the south and west. High temperatures will be in the single digits to teens.
LONG TERM. (Tuesday night through Monday) Issued at 220 PM CST Mon Dec 9 2019
Surface ridge builds into the Upper Great Lakes quickly Wednesday and forecast area will be dry. Arctic airmass will allow temperatures to be well below normal . with highs rising to around zero to the teens.
Focus turns to Wednesday night into Thursday . vigorous shortwave trough quickly tracks across the Northern Plains/Upper Midwest. The 09.12z GFS/NAM are in good agreement with decent forcing/isentropic lift in association with the shortwave trough Hence. the deterministic models are suggesting slightly higher qpf amounts than previous runs. With temperatures through atmosphere column below freezing . precipitation type should be all snow and the higher qpf will result in slightly higher snowfall amounts. Have increased qpf and snowfall amounts slightly . based on the stronger forcing/lift with the shortwave trough.
Main forecast concerns are precipitation chances Thursday night into Monday. The 09.12z deterministic models are in good agreement with overall west to northwest upper level flow pattern through the period. Biggest issue during the period is timing the pieces of energy embedded in the upper level flow across the northern tier states/Upper Midwest Depending on temperatures. precipitation types will be an issue . as the deterministic models suggest a couple of days temperatures are expected to be near or above freezing.
AVIATION. (For the 06Z TAFS through 06Z Tuesday night) Issued at 1125 PM CST Mon Dec 9 2019
Cigs/WX/vsby: Low, mostly mvfr deck making slow, steady progress east - just clearing KRST now with satellite trends suggesting moving east of KLSE between 06-07z. Could see a mid level sct-bkn VFR deck for Tue morning but then some hints via RH fields that a few hours of MVFR could develop for Tue afternoon. Decent low level lapse rates and cold air advection to promote the SC that could lead to some flurries too. With Bufkit RAP/NAM showing this potential, going to tempo in a few hours.
Winds: holding west and mostly around 10kts or so through Tue, with some slight shift down and to the southwest for the evening.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
