  Thunder and Lightning

Posted: 12/19/2008 10:08:00 AM

An excellent display of a very dynamic system heading towards the region right now. Looking at reports upstream, there have been lightning strikes from Illinois into Ohio and Michigan. This along with latest mesoscale model runs indicating a good environment for frontogenesis along the Mass Pike supports the possibility of strong banding and thundersnow this evening. Snow could fall at rates of 2 to 4 inches per hour in central Massachusetts around 5pm to 8pm.

Here in Keene, still no changes. Model guidence supports at least .7" water equivalent now. This adds confidence to the possibility of 10" here. Will continue to monitor radar trends to see whats ahead. For now, no significant deviations from the expected.

Sunday is looking good still. Will have a full discussion and first map later today.
