Significant Weather Outlook: Monday, March 9, 2026
Weekly Significant Weather Outlook
The big meltdown continues at least for the first half of this week. From a significant weather perspective, the main issue is likely to be the risk of river and small stream flooding. High temperatures through Tuesday are expected to reach well into the 60s and perhaps even near 70 degrees in a few spots on Tuesday. It’s expected to turn cooler late in the week. There could be a few episodes of light precipitation during the second half of the week and possibly over the weekend. Precipitation associated with a cold front Thursday night may end as snow over the higher terrain. The runoff from melting snow will cause streams and rivers to swell with a risk of minor flooding (especially along vulnerable portions of the Connecticut River). If we should encounter a heavier rain event this week (not presently looking likely), then there could be a risk of more serious flooding. Will issue message blogs this week if there should be a threat of more than minor river/stream flooding. In addition, the melting snow may result in some flooded basements for those homes susceptible to such.
