Warm and Dry Start to October
Warm and Dry Start to October:Following the trend from September, through the first 8 days of October temperatures around Minnesota are averaging from 3°F to 6°F above normal. October 6 brought high temperatures in the 80s F to many areas in the state and included a reading of 88°F at Marshall (Lyon County).
In the dry air of October, frosts have occurred in 18 northern and central counties, with many observers reporting low temperatures in the 20s F. Very dry air has been dominant in many areas of Minnesota, especially western counties where relative humidity values have been as low as 14 to 16%.
Rainfall so far this month has been scarce, with many areas reporting less than a tenth of an inch. A few scattered thunderstorms have brought over an inch of rainfall to some areas. The observer in Northfield (Rice County) reported over 1 inch of rain on October 3rd. No snow has been reported in the state so far this month.
The latest U.S. Drought Monitor shows 33 percent of the state landscape in Moderate Drought, 24 percent in Severe Drought, and 3 percent in Extreme Drought. According to USDA reports dated October 4th, crop harvesting weather has recently been good and 12 percent of the state’s corn has been harvested, while 25 percent of the soybeans have been harvested.
A further climate note: according to NOAA data, Minnesota has recorded a warmer than normal October on a statewide basis for 5 consecutive years now, and 2026 may add to that streak. In addition, 3 of the last 4 Octobers have been drier than normal on a statewide basis.
Weekly Weather Potpourri:The NOAA-National Hurricane Center has been tracking Hurricane Isaias in the Gulf this week and issuing advisories and forecasts. The hurricane is expected to strengthen before making landfall somewhere between the coast of eastern Mississippi, along the coast of Alabama, or even the panhandle of Florida beginning later the day on Friday or early Saturday morning.
According to the BBC, the current strong El Nino episode has brought some record-setting rains to central Chile in South America. Some areas have recorded their wettest October in 76 years and flooding has caused evacuations to occur in some areas. More rain is expected there for next Monday through Wednesday.
The Bureau of Meteorology in Australia has concluded that overall, the country recorded its 2nd warmest month of September in history. Further, the outlook for the October through December period is for warmer than normal conditions to prevail, with expectations for some extreme summer heat in the coming months. The outlook also favors above normal rainfall for much of central and western Australia.
MPR listener question:Several of us at Al’s Corral in South St Paul were watching the news about Hurricane Isaias in the Gulf this week (we have friends who are fishing the Gulf), and we wondered how long ago did the National Weather Service begin its hurricane forecasting service?
Answer:The National Weather Service initiated a 24 hour hurricane forecast and warning service in 1935, initially at Jacksonville, FL. It moved to Miami in 1941 to co-locate with aviation and military operations. Actually, the organization made an initial serious attempt to forecast hurricanes during the Spanish-American War in 1898. This effort was intended to support the U.S. Naval forces operating in the Caribbean Sea and Gulf of Mexico. I don't know how successful this first forecasting service was.
