12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 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. |

SHORT TERM. (Today through Thursday) Issued at 327 AM CST Wed Feb 19 2020
A cold high pressure has settled over North Dakota this morning, which has produced light winds and clear skies, with nearly ideal radiational cooling conditions. Temperatures have dropped to zero to around 10 below over a broad stretch of the forecast area as of 3AM, and there are a few more hours of cooling to go. Overnight lows of 10 to 20 below are working out so far, but would not be surprised to get some local values colder than 20 below once reports start coming in later this morning. This ridge of high pressure remains over the area today and tonight, which should keep our skies mostly clear and winds generally light. The cold airmass in place over the area and the cold start this morning is going to keep us from getting very warm today, but the generally dry airmass should allow a large diurnal range with highs getting into the single digits to around 10 above. Tonight will be cold again with the surface ridge axis overhead and light winds winds. However, warm air advection will be going on aloft and have seen this put a damper on extreme cold in the past. For now have put lows in the 5 to 15 below range, but would not be surprised to see us get colder in spots. The west-southwest winds should be picking up a little towards morning and may produce another night of painfully cold wind chill values north of the Iron Range. Another Wind Chill Advisory may be needed tonight, but will leave that for the day shift to re-evaluate.
LONG TERM. (Thursday night through Tuesday) Issued at 327 AM CST Wed Feb 19 2020
The long-term forecast period continues to show dry conditions at least through the upcoming weekend, along with temperatures warming to well above seasonal average for Friday through Monday.
Thursday night will have the large area of high pressure that will keep conditions quiescent for the next few days south of the region over the mid-Mississippi River valley region. This area of high pressure will gradually sink southeastward, eventually settling over the southeastern CONUS, leading to persistent southwesterly flow over the Northland, and strong warm air advection. The air mass in the wake of the departing high appears to be very dry, so there are no concerns for any precipitation through the weekend. However, with the warm air advection over our deep snowpack, coupled with melting snow and ice, I would not be surprised if we had issues with fog/low stratus over much of the region if dew point depressions can decrease. High temperatures for Friday through Monday of next week will warm into the middle to upper 30s over most of the Northland. Expect breezy southwest winds due to a tight surface pressure gradient over our region. Gusts could range between 20 to 30 mph at times during the day Friday.
Generally zonal flow aloft will continue through the upcoming weekend before some amplification in the upper-level flow develops over the Pacific Northwest. A strong upper-level jet will help dig a longwave trough, leading to a mid-level shortwave trough ejecting into the Northland for Tuesday and Wednesday of next week. This appears to bring our next chances of precipitation, in the form of snow. Both the GFS and ECMWF models indicate only some light snow associated with this shortwave, so nothing significant by any means, particularly given the lack of strong large-scale forcing. Temperatures do appear to cool closer to average for Wednesday, with highs in the 20s across the region.
AVIATION. (For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1130 AM CST Wed Feb 19 2020
A large are of high pressure will slowly move through the upper Midwest Wednesday through Thursday, with VFR conditions. Breezy winds are possible Wednesday afternoon across northern MN through about 00Z. Northwesterly winds will gradually shift to southwesterly by Thursday morning, before wind speeds look to increase across the region by 18Z.

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. |
