Heaviest Rain Gone, But the Miserable Remains
Our dry spell has been broken by a storm system that pushed from Wyoming and Nebraska into the Dakotas overnight (see infrared loop from College
of DuPage Satellite and Radar Menu). There were thunderstorms involved in west central Minnesota yesterday afternoon and in southern Minnesota overnight. The heaviest rain totals have been in southern Minnesota with Fairmont getting 2.78 inches, Jackson 1.37 inch, Rochester reporting 1.36 inches, and New Ulm 1.09 inch as of 3 AM. In central Minnesota, Morris picked up 1.74 inch, Ortonville 1.15 inch, Paynesville has seen 0.99 inch, Sauk Centre had 0.94 inch, Long Prairie had 0.62 inch (with some occasional sleet mixed in), Little Falls had 0.53 inch, Buffalo had received 0.45 inch, and the St. Cloud Airport has picked up 0.70 inch through 7 AM (see NWS: Last 72 hours of St. Cloud Observations). This has pushed October rainfall back above average to 2.47 inches (see St. Cloud preliminary October high-low temperature table from the National Weather Service).
As the main low has pushed to the western border of Minnesota in the early morning hours (see water vapor loop from College
of DuPage Satellite and Radar Menu), most of the heavier rain showers have pushed further to the east or stayed across south central and southeastern Minnesota (see NWS
Upper Mississippi Valley radar loop). However, with all of the rain locally and an east wind continuing to blow in air where the rain showers will remain, we will likely have light rain or sprinkles for a good chunk of the morning and lingering clouds for most of the day. There may be a few sunny breaks this afternoon. All of the clouds and the moisture won't allow much heating from the early morning temperatures in the low to middle 40's (see UCAR
Minnesota surface chart). If we get a bit of sunshine, temperatures may have a shot at 50 degrees, but that will about do it.
Clearing will most likely hold off until tonight. Still, with the overnight rainfall, some fog is possible in central and southern Minnesota. Temperatures will drop to the middle 30's.
The drying process will begin tomorrow with partly sunny skies and temperatures returning to the near average middle 50's. The next storm system will stay mostly north of the Canadian border as it pushes through Friday into Friday night. There might be a chance of a late day shower on Friday into Friday evening, but with a lot of sunshine, high temperatures should climb back into the 60's.
The low will pull its cold front through Minnesota early Friday evening, so temperatures will fall back into the 30's by Saturday morning and only rebound to the lower half of the 50's by afternoon. Expect a rather chilly Saturday night with temperatures bottoming out near freezing. We'll be back on a warming trend after early Sunday with highs back in the upper 50's on Sunday and possibly back into the 60's on Monday.
The overall weather pattern will continue to feature strong storms periodically pushing into the West Coast, continuing the coastal rains and Washington State snows seen over the past week. Those storms will push inland, but several of them won't have a lot of moisture left over from their mountain trip. The frequent storms, however, will continue to supply us with a roller coaster of temperatures into next week.
There is a late season Pacific hurricane to the west of Mexico. Hurricane Seymour is extremely strong with top winds of 150 MPH. The storm is moving westward, but is expected to curve to the north through the end of the work week. Winds aloft and warm ocean water are favorable for the storm to remain strong today, but weakening is expected tomorrow and Friday. Major effects on land are not being forecast.
