NorthShoreWx Posted January 30, 2015 Share Posted January 30, 2015 And the southern winds are rather light, so yes I agree. Ditto. I see too much model reading where the surface freezing line on MOS is taken as gospel, not to mention as the snow line, despite a cold column and weak or no low level WAA. I've seen clippers go from expected snow to rainers with stronger than anticipated WAA (12/1989 was notable), but most of these things are all snow when they look like this one does. Possible exception is the immediate south shore if the precip is light and there is enough steam pouring off of the tea kettle. Link to comment Share on other sites More sharing options...
EasternLI Posted January 30, 2015 Share Posted January 30, 2015 Agreed. Upton agrees also: RIDGE OF HIGH PRESSURE CONTINUES TO MOVE OFFSHORE AS A CLIPPERSYSTEM APPROACHES FROM THE WEST. A SHORTWAVE EMBEDDED IN A DIGGINGUPPER TROUGH WILL PROVIDE LIFT FOR LIGHT SNOW TO DEVELOP THISEVENING. HAVE CATEGORICAL POPS BY LATER TONIGHT. WARM ADVECTIONAHEAD OF THE LOW WAS RAISING BOUNDARY LAYERTEMPERATURES...HOWEVER...PROFILE SHOULD REMAIN COLD ENOUGH FOR ALLSNOW. WARM AIR MOVING IN OVER THE WATERS WILL ALLOW FOR RAIN ANDSNOW OVER THE WATERS AND A SLIGHT CHANCE THAT ENOUGH WARM AIR MAYMOVE IN ACROSS THE VERY FAR EASTERN ZONES FOR A MIX OF RAIN ANDSNOW. TEMPERATURES WILL HOLD NEARLY STEADY OR ONLY FALL A FEWDEGREES TONIGHT. FOLLOWED CLOSER TO THE COLDER NAM TEMPERATURESAND TRENDS. Link to comment Share on other sites More sharing options...
