Forecast – Friday, September 12

Current Conditions:

Conditions this fine Friday afternoon in central Minnesota are mostly cloudy with highs in the low 50s.  Winds are about 5mph from NW.

Short term forecast: One more chilly night awaits you tonight with another frost advisory and lows in the low 30s.  Tomorrow will be warmer with a high around 60 and low near 40 on Saturday night.  A center of high pressure over Kansas/Missouri will induce 10 mph winds from the south on Saturday.  There is a chance of slightly higher (15 mph) winds Saturday afternoon.  Warmer and partly sunny conditions will prevail over the weekend. A weak trough will pass through Sunday afternoon bringing a chance of light rain.

Long term forecast:

After the weak front/trough pulls through on Sunday, high pressure will build back in and provide a sunny Monday with highs in the low 60s.  This fair weather should persist through Thursday.

Aurora forecast:

40% chance of a major radio blackout tomorrow! There’s currently a G2 (moderate) geomagnetic storm! Current Kp index is around 5 and predicted to increase to 6, which indicates high potential for seeing the aurora in the midlatitudes tonight — one website estimates a >30% chance of seeing the aurora tonight in the midlatitudes.  The second coronal mass ejection should arrive tomorrow, making Saturday night also a good night for potential aurora in the midlatitudes.
