Original post on Facebook #Maine #MEwx THURSDAY March 21st Update…
THROUGH FRIDAY… WIND and WINDCHILL are the main themes as the current storm departs. Gusts of 25-45 mph are possible south of the mountains, with higher gusts for the taller peaks, where 60 mph gusts potentially reside. ISOLATED POWER OUTAGES are possible. The cold coming in sets the table for the next storm on the way to start the weekend. THE NEXT ONE… WINTER STORM WATCHES are being posted on the heels of the current system. Western areas have theirs already, and northern areas should see them go up later in the day. STORM STARTS OFF AS SNOW EVERYWHERE, with flakes on the ground over the south and west by daylight Saturday. Eastern and northern areas see snow begin to fall Saturday morning. A FRONTAL BOUNDARY STALL OFFSHORE DICTATES THE PRECIPITATION-TYPE AND AMOUNT OUTCOME. The pink dash line I have on the map shows the idea of the northerly advancement of junk potential as of early Thursday morning. THERE REMAINS DISAGREEMENT WITH GUIDANCE ON WHERE THE STALL TAKES PLACE. A more easterly stall means less junk and more snow, and a more westerly stall means less snow and more junk. Confidence is fair for an all-snow event north of the pink dash line. WIND does not appear to be much of a factor on the front end of the storm, but expect a breezy, if not windy, Sunday in the wake of the system. THE STORM ENDS Saturday night over the south and west and Sunday morning over the north and east. Chances are fair that the storm will end as snow or junk. Coastal areas that get rain are likely to see it freeze heading into Sunday morning. Ah, spring storms. So much fun! Stay tuned! – Mike |
