Last week’s forecast was a bit hit and miss. We did see some heat move in, late in the week, as the upper ridge finally moved in, but a couple of upper-level disturbances brought some pretty unsettled weather over the weekend, along with much cooler-than-expected temperatures.
For this forecast period, it looks like our active weather pattern will settle down, but just a little bit. To begin this forecast, the weather models show yet another upper low that may impact our region. So far the models have kept most of the clouds and thunderstorm activity from this low to our south for Wednesday, but the way things have been going this year, we can’t rule out the chance of thunderstorms over extreme southern regions early Wednesday. Things will then dry out late Wednesday and Thursday before the next weak system pushes through Friday. There will be enough instability with this system to kick off a few widely scattered thunderstorms during the day on Friday. Temperatures during this period will be in the mid- to upper 20s if there is sunshine; otherwise, expect low 20s under the clouds.
Over the weekend a fairly deep area of low pressure is forecast to track across Northern Canada. While this system will not affect us directly, the low will pull down cooler air behind it as it tracks into Hudson Bay. Expect daytime highs on Saturday to be fairly warm, with a bit of a cooldown on Sunday and Monday. Anticipated highs should be in the low 20s with a good chance of some scattered afternoon clouds, along with maybe the odd shower.
Things should then clear out and warm up for Tuesday and Wednesday as high pressure builds to our southeast. We can probably expect more showers and thunderstorms later next week as more Pacific energy pushes eastward.
Usual temperature range for this period: Highs, 20 to 29 C; lows, 7 to 15 C.
