Roger Smith Posted February 26, 2013 Share Posted February 26, 2013 Ontario forecast -- mixed precip will change to all snow about 9 p.m. in the Lake Ontario region, and this will become heavy, giving 20-30 cm (8-12 in) accumulations by mid-day Wednesday followed by a further 1-3 cm in sporadic light snow for another day or so. Eastern Ontario will see 30-50 cm amounts mainly on Wednesday night into Thursday morning. About 15 cm for Hamilton to London and 10 cm in southwestern ON. Reasoning -- storm is already largely occluded and coastal wave is weak at surface but has large amounts of moisture available for over-running. As thicknesses and 850 mb temps collapse southward after onset of precip, aided by nocturnal cooling effects, this storm will become mainly snowfall even in some parts of w NY so the meagre warmth of Lake Ontario will not be enough to change phase except possibly at times near Toronto Island. Storm will tend to gain a second boost of energy when it transfers most of its circulation to the New England centre and this will increase the snowfall rates in eastern ON (and upstate NY, Quebec, VT-NH) compared to what is recorded in southern ON. For US regions same general thinking, MI should turn to all snow shortly after sunset and most of OH - n/c IN will see more snow than sleet at some point before the storm ends. This storm may also do better in southern New England and the Hudson valley than some are expecting as it seems bent on expelling all traces of warm air in its surface circulation.

on_wx Posted February 26, 2013 Share Posted February 26, 2013 Well we've been stuck between 2.6-2.9c the last 3 hours or so. Good news is that sfc dewpoints are below freezing by a few degrees so we shouldn't have any problem shedding the warmth when the precip starts. That beings said, most south of the 401 should prepare themselves for at least an hour or two of RASN. Wloo is at 1.2c with a td of 0.7c temps have been on a steady decline from 2.9c at 1245 Link to comment Share on other sites More sharing options...

mjwise Posted February 26, 2013 Share Posted February 26, 2013 Snow/Mix line appears to be a line extending from ADG-YIP/ARB-OZW now. It is just SN at ARB now. Trying to watch radar to see signs of ice pellets or rain mixing back in. Don't think we're going to get a switch back now? Window for a switch back would seem to be closing west of US-23 or so.
