![]() High temperatures could be 10 degrees off either way any day from Tuesday on.ĭetailed St. With such widely varying scenarios, note that the precipitation scenarios (not only type and amount, but whether we get any at all, along with temperatures) are very uncertain. The disagreement between the scenarios is so strong that the European forecast has a cool high pressure over us on Thursday, while the US forecast has a major storm over us with rain in our area and even a chance of snow to our west (see Days 6 and 7 on the NWS Winter Weather Outlook). The edge of the cold air will be close enough to droop southward, allowing a chance of showers and thunderstorms on Monday night into perhaps Tuesday.Īfter that, we have all the possibilities I ran down yesterday: we could be a) in the area where the two flows come together and could see significant rain (that scenario is shown on the Days 4-7 NWS WPC quantitative precipitation forecast), b) stay on the warm side for a while if the Intermountain low stays in place, c) get much cooler if the Siberian low pushes south, d) none of the above. Meanwhile, the flow near the US-Canadian border is likely to be west-to-east through Monday or Tuesday, so we could see another breezy and warm day on Monday. At the same time, the really cold air will push well into the Prairie Provinces. ![]() The Aleutian low is still forecast to move into the Intermountain West, drawing the leftover moisture from Hurricane Norma (see Pacific clean infrared satellite loop from Colorado State satellite slider) northward to get involved with any front in the area. The moving pieces remain the low over the Aleutian Islands (see Pacific Mid-tropospheric water vapor loop from Colorado State satellite slider), the first substantial wave of cold air of the season now over northern and central Alaska (highs in the 20's and 30's see 4 PM Thursday NWS WPC North America zoom-in map), and another low on the Alaska-Yukon border. The forecast for next week is still about as uncertain as what Taylor Swift will wear to her next Kansas City football game. Highs will be in the 50's to near 60 Saturday and in the upper 50's to perhaps 60 on Sunday. The cold air pocket aloft will allow a lot of midday and afternoon clouds to develop both weekend days, and there might be a few sprinkles, but any rainfall will be similar to what we saw the past couple of days. That will give us another shot at cooler air, although our highs in the middle or perhaps upper 50's are now 5 degrees warmer than the rapidly dropping October averages (53 or 52 degrees over the weekend). The Canadian storm will replace the eastern storm and intensify through the weekend, allowing northwest-to-southeast steering winds to blow from the Canadian Prairies through the Great Lakes. Cloud area), so even getting puddles will be difficult. However, there is even less moisture with this system than we had with the Wednesday system (set to daily data for a month and set the month to 2023-10 and the station to St. The cold front from this storm will move through during the early evening. Highs today will climb well into the 60's and may have a shot at 70 degrees. In advance of the storm, there aren't many clouds so, once we get rid of the early fog, we will see the warm temperatures that extend from Montana and the Dakotas well into Alberta and Saskatchewan (highs in the 70's in the south, highs in the 50's near the Nunavut border see 4 PM Thursday NWS WPC North America zoom-in map). This storm will reach the Ontario-Minnesota border by tomorrow morning. The next storm is moving through northern Alberta and Saskatchewan (see Mid-tropospheric water vapor loop from Colorado State satellite slider). ![]() However, the clear skies and light winds have allowed areas of dense fog to develop in central Minnesota (see stations with horizontal lines on the NWS Aviation Weather Center METAR map). We are finally clear of the persistent low clouds (see GeoColor loop from Colorado State satellite slider) that have hung around in the wake of Wednesday's storm (now in Ohio see mid-tropospheric water vapor loop from Colorado State satellite slider). ![]() Prepared by Bob Weisman, SCSU Meteorologist and Professor Emeritus Bask in Today's Warmth.After the Fog Breaks Up
