DAYS 1-5 (FEBRUARY 4-8)
Making a few adjustments. I like faster timing of features during this 5-day period. A weak wave of low pressure may bring a little light rain to areas mainly south of I-90 today to early Wednesday, with mild air today giving way to a more seasonably chilly day Wednesday. And then we have a 1-2 punch of low pressure areas Thursday and Friday. Enough cold air will be around for the first one to start as snow Thursday morning, probably pre-dawn, in most of the region except the South Coast which probably starts as rain. Generally minor accumulation is expected from this before enough warm air takes over to change it to rain, followed by a lull, then another slug of rain for early Friday with a second low center moving up over New England. But this system will be hauling and will already be on its way out Friday afternoon. It currently appears that the end of the moisture will beat the arrival of colder air, so I’m not expecting anything more than a passing snow shower as colder air returns, setting up a fair and seasonably chilly day for Saturday, or a nice start to a mid winter weekend. Will that last? See the DAYS 6-10 section after you check out the detailed forecast for the next 5 days…

DAYS 6-10 (FEBRUARY 9-13)
A wave of low pressure brings the risk of snow/mix February 9, but this will be a small area of low pressure so a subtle shift in its track would mean a significant difference in weather here. It could end up further south and largely a miss, but a little early to know for sure. Interlude of drier weather February 10-11 before another low pressure area brings unsettled weather later February 12 through February 13, based on current timing.
DAYS 11-15 (FEBRUARY 14-18)
Unsettled pattern continues with another risk of precipitation, possibly a longer-duration event, favoring the second half of the period.
