Forecast: Summer looks to move back in

Issued June 26, 2017 – Covering the period from June 28 to July 5, 2017

Well, once again our weather was hijacked by not one, but two upper lows. The first one brought the cool and cloudy conditions late last week. That low then pulled off to the east as expected, but another upper low was captured in the northwest flow behind the first upper low and we saw a continuation of very cool and unsettled conditions right through the weekend.

For this forecast period it does look like summer will be making a comeback; it just looks like it will take until July for that to happen. This forecast period will begin with another area of low pressure slowly moving through our region starting Wednesday. Most regions will likely see showers and thundershowers sometime Wednesday and into Wednesday night before the main energy pushes off to the east. A second weaker low will follow behind the main low, giving us a mix of sun and clouds on Thursday and Friday along with the odd shower. Temperatures don’t look as if they will be as cool, with daytime highs expected to be right around 20 C.

High pressure is then forecast to build in over the weekend and into the first half of next week. Under this high we should see mainly sunny skies along with warming temperatures. Daytime highs will start off in the low 20s on Saturday and warm up a couple of degrees each day, with highs expected to be in the upper 20s by next Tuesday or Wednesday. Overnight lows should be in the 11 to 15 C range.

Looking a little further ahead, the weather models show a couple of fast-moving systems during the second half of next week. They should bring typical summer-like weather, with short periods of clouds along with a few quick showers before sunny skies move back in. Temperatures look to remain warm.

Usual temperature range for this period: Highs, 21 to 30 C; lows, 9 to 16 C.
