Spring warmth feels so good
We can expect one more day of above normal temperatures before a cold front drops us down to near normal for Thursday and Friday. The overnight low will remain above freezing tonight leveling off at 3C (38F) before a high Wednesday of 6C (43F). Gusty southwest winds of 30-60km/h will develop and last into Wednesday along with increasing clouds and perhaps some light showers. Skies will clear out late Wednesday with colder weather and a low into Thursday morning of -8C (18F). Thursday and Friday will be fair with cooler highs near 0C (32F).
MARCH SNOWSTORM?
By Saturday morning, models are starting to come into agreement in bringing two low pressure areas, one from the southern US and another from the Great Lakes, northeast into New England. A surge of moisture along with mild air should arrive in southern Quebec and Ontario by Saturday. It may be just cold enough in Montreal and the St. Lawrence Valley for snow on Saturday. I am watching the different scenarios closely and hope to get a better handle on the weekend forecast within the next 24 hours. If the precipitation falls as all snow, amounts could be more than 10cm (4 inches). Some rain may be possible as well. Skies will clear by midday Sunday with a return to sunshine and milder weather.
