"Saving Lives through Education"
More unsettled and cooler weather is on tap for the rest of the week, but how much precipitation falls remains the big question.
While models are in good agreement on the overall global patterns, they are not in very good agreement on when, where, and how
much precipitation will occur in the days ahead. This is due in part because of the swift Westerly flow which causes a
rain-shadow affect of sorts, and causes most of the precipitation to fall in the higher terrain. Even so, the conditionally
unstable atmosphere will result in scattered showers and thunderstorms at times, some of which could contain graupel or
wet snow, depending on the timing.
Models continue to lean toward a cool, unsettled weather pattern going right into the Easter
weekend. Showers of rain, wet snow, snow pellets, or small hail will be possible at any given time, along with
breezy to windy conditions. As with the early part of the forecast period, precipitation amounts remain uncertain.
Temperatures are expected to dip below normal as a winter-like trough of low pressure settles over the area into early next week.
