High pressure begins to move well offshore tonight and Thursday. A vigorous storm system will emerge out of the Plains to be positioned in the western Great Lakes by midday Thursday, then to a position north of Quebec City by Friday night. This storm will be the main focus for our weather starting late Thursday into Friday and will continue to have impacts into the weekend as well.
Tonight we remain tranquil as skies cleared up nicely during the mid and late afternoon hours today and they should remain generally partly cloudy through the overnight. Some areas of patchy fog develop late tonight with a very light wind. Low temperatures in the 30s.
Thursday will see skies cloud over quickly and rain showers may break out during the afternoon. The low pressure system pulls warmer air northward on gusty south to southwest winds, especially during Thursday night. The showers will transition to a steady rain at night that is likely to be heavy at times after midnight. Highs Thursday will climb into the low 60s and only fall a few degrees through the night, hovering in the upper 50s, making for a very mild night for the end of October. Winds could gust to around 40 mph after midnight making for a windswept rain through the night.
Friday morning will start off windy and rainy but the rain will taper off during the morning with occasional showers lingering into the early afternoon. By mid or late afternoon we could see a few breaks of sunshine. Highs climbing well into the 60s, perhaps a few communities reaching 70 degrees. Not bad for the first day of November. Southwest winds will howl at 15 to 35 mph, perhaps higher in some gusts.
Friday night, the low in Quebec swings a cold front through here early bringing a chance of a shower, otherwise partly cloudy, breezy and cooler. Lows in the 40s. Winds becoming west 10 to 20 mph with some higher gusts in the evening.
The weekend will be changeable. Saturday starts off with sunshine but clouds fill in as a secondary cold front approaches. Ahead of the front temperatures likely push into the low 60s. Once the front moves through on Saturday night it becomes much cooler with the mercury dipping back into the 30s by Sunday morning. There is a chance of a passing shower late in the day or during the evening as the cold front approaches and then makes its pass through here Saturday night. Expect breezy if not windy conditions Saturday and Saturday night.
High pressure follows behind the front Sunday and it will be a much cooler and breezy day. Early sunshine may give way to a partly cloudy afternoon. Highs in the upper 40s to low 50s, with lows falling into the upper 20s to low 30s overnight.
More of the same is expected on Monday as it stays breezy and cool.
