Weather is business and a number of private services are highly trained specialists to provide specific weather details to clients. You are familiar with The Weather Channel. Earlier this season they announced when a winter storm reaches a certain criteria they will bestow a name.
The Weather Channel named this storm off the East Coast Athena. Local NWS offices were informed not to use this name when referencing this storm in statements and warnings:
“TWC HAS NAMED THE NOR’EASTER ‘ATHENA.’ THE NWS DOES NOT NAME
WINTER STORMS IN OUR PRODUCTS. PLEASE REFRAIN FROM USING THE TERM ‘ATHENA’ IN ANY OF OUR PRODUCTS.”
Makes for an Interesting side story. Forecast accuracy to enhance public safety is a priority with the NWS, working with emergency and public officials.
Closer to home, the Twin Cities enjoyed a brief period of sunshine today. Ninety minutes of sun did little to boost the thermometer. Temperatures held mostly in the middle 40s through the afternoon hours.
Not much in the way of precipitation is expected in Minnesota through Friday. Temperatures will be at or near normal. Highs in the 40s to lower 50s with overnight lows in the upper 20s and 30s.
The storm we have been anticipating for the weekend does not appear to be as potent on the last computer run from the NAM. We still expect a nice warmup on Saturday for southern MInnesota. Precipitation totals do not look very significant in the Twin Cities
NAM forecast for Saturday. Pressure pattern and precipitation at 3 p.m. CST. Our best chance for precipitation may come with the blast of colder air Saturday night. Source:NOAA/College of Dupage.
The National Weather Service in Grand Forks will track this storm to evaluate the potential for wintry weather in eastern North Dakota on Saturday.
