A La Nina Watch has now been issued. NOAA predicts a 70% chance of La Nina developing this fall and a 55% chance of it persisting into winter.
Cooler than normal water in the Pacific Ocean can mean a cold winter in Minnesota. My hunch is that La Nina conditions will begin to fade throughout winter so the impact won't be as great.
The three images below show a temperature departure from normal forecast for meteorological winter (December, January, February). While December does look warmer than average, this warm bias begins to fade slightly by January only to beef back up again in February.
A warming trend continues through next week. More Pacific air in origin is streaming over Minnesota helping to deflect any cold, Canadian air north of the state. We have yet to see a hard freeze this season.
The singletrack is drying out. No big precipitation events for the metro anytime soon. And that's just fine. The precipitation since the beginning of summer is already above average as we make a run for one of the top wettest years on record.
Summer brings warm afternoons perfect for biking, but the summer heat and humidity can also spark thunderstorms and severe weather. Be prepared for any type of adverse weather headed your way with Aeris Pulse.
