With the unsettled pattern continuing to persist across our region, last week’s forecast did not do too bad of a job. We did see temperatures moderate into the low to mid-20s. The strong area of low pressure did develop to our west last weekend, which allowed warmer-than-expected air to push northward — then more unsettled weather moved in behind this short-term heat wave.
For this forecast period, it looks like we will continue to see unsettled weather, which translates into the chance of showers or thundershowers every few days, and some warm days intermixed with the odd cool day. Trying to nail down the details with this type of forecast is difficult, but here is what the big picture looks like.
We should start off with a predominantly westerly flow across our region with weak areas of low pressure rippling along this flow. This means we will likely see a mix of sun and clouds from Wednesday to Friday, along with the chance of afternoon showers or thundershowers. Daytime highs will be in the low to mid-20s with lows in the 12 to 14 C range, which is right around average for this time of the year.

Thunderstorms and straight-line winds
Straight-line winds in thunderstorms can cause as much damage as a tornado and are next on our weather school list exploring how and why severe summer weather forms.
Over the weekend it looks like weak high pressure will move in, bringing mostly sunny skies, light winds and daytime highs warming into the mid-20s. Late in the weekend or early in the last week of June, the weather models show the flow across our region becoming southwesterly once again. This means we will see a return of unstable weather. Expect temperatures to stay warm, with daytime highs in the mid- to upper 20s along with the chance of showers and thundershowers nearly every day.
Usual temperature range for this period: highs, 21 to 29 C; lows, 8 to 16 C.
