Precipitation:
OVERVIEW: The month of March we project a near average precipitation departure (-0.5″ to +0.5″) for the month as a whole, which was maintained as the projection from last week with a generally unsettled pattern…but not overwhelmingly so in terms of quantitative precipitation during the final week of the month. It is also likely that snow and wintry precipitation is largely done for this season everywhere, with the exception of a few arbitrary flakes in northern areas still possible. The month of April we also maintained near to slightly above average precipitation for the month as a whole with near average snowfall or none at all, but snowfall in April at all climate locations are generally under an inch.
Shorter term, low pressure cutting through the Great Lakes Friday night will drag a warm front northward through our region with showers, then as a secondary low pressure develops SE of the region Saturday, additional showers are likely during the day, wrapping up Saturday evening. A couple of weak shortwaves will move though the region early to mid next week with showers, but not occurring during that entire period. The next organized system will be similar in nature to the Saturday 3/25 system with a cutting primary low into the Great Lakes with secondary low development, and brings the threat of rain at the end of next week in the Friday-Saturday time frame.
The month of March’s projection is for a near average (-0.5″ to +0.5″) precipitation departure for the month as a whole, with snowfall likely already having occurred this month. The last week of March will be unsettled on several occasions, but precipitation appears to be generally near average during that week as a whole. Our projection for the month of April was maintained this week for a near to slightly above average (+0.0″ to +1.0″) precipitation departure for the month as a whole, using longer term climate models and global observation trends.
