As forecasted last week, a ridge of high pressure developed over our region during the first half of this week, bringing sunny skies and warm summer temperatures. This ridge of high pressure looks like it will begin to break down starting on Thursday, and we’ll begin a slow transition into cool temperatures.
After a really warm start to the week that saw temperatures near or even above the usual temperature range for this time of the year, it looks like we will see a change in the weather pattern beginning on Thursday. The confidence in this forecast is not that high, as the models have been bouncing around a little bit, but here is what they show.
Starting Thursday, the ridge of high pressure will begin to break down as a large area of low pressure to our west begins to move eastward. It looks like this ridge will try to stay in place on Thursday and Friday, but we will see increasing moisture and clouds as the low moves closer. By Friday there will be a good chance of seeing a few showers or thundershowers, along with a mix of sun and clouds. We might see a bit of a break on Saturday, before the main area of low pressure moves into our region on Sunday.
We should see increasing clouds on Sunday along with a good chance of showers and thundershowers. This low looks like it will take its time moving through our region, with clouds and showers sticking around until at least Tuesday. The best chance of significant rain looks to be over northern regions. Temperatures will cool down each day, with Tuesday looking to be a fairly cool, blustery day.
Looking further ahead, the weather models show us moving back into an early-summer pattern, with temperatures warming back into the low to mid-20s by late in the week.
Usual temperature range for this period: Highs, 18 to 28 C; lows 6 to 15 C.
