After a cool start to the week, thanks to a region of cool polar air, it looks like nice fall weather is going to return for the rest of this week and next.
By Wednesday, cool high pressure will be sitting to our east and we should start to see a warm southerly flow around the back side of the high. This southerly flow will continue into Thursday, allowing temperatures to warm back up into the low 20s for highs. Humidity will also increase, with some clouds and widely scattered showers possible late Thursday or Friday. The best chance of showers will be over extreme southern regions.
Over the weekend a large area of low pressure is forecast to move into northern Canada from the Gulf of Alaska. This feature, combined with high pressure sitting to our east, will give us a dry westerly flow resulting in plenty of sunshine and continued warm temperatures. By Sunday I wouldn’t be surprised if we see temperatures at or above the high end of the usual temperature range for this time of the year.
It looks like some of the energy from this northern Canadian low will make its way into our region Tuesday or Wednesday of next week, bringing with it clouds, a few showers and cooler temperatures. At this time it doesn’t look like we’ll see any significant rainfall, and while temperatures will be cooler it doesn’t look like frost will be likely.
Further ahead it looks like this pattern will repeat itself. The weather models show another strong area of low pressure moving back into northern Canada from the Gulf of Alaska late next week.
Usual temperature range for this period: Highs, 13 to 24 C; lows, 2 to 11 C.
