 A look here at the big picture at the 500mb steering level of the atmosphere shows the players on the forecast table through the start of next week. The Trans Canada Highway aloft is in overdrive with two clippers, the first passing through Thursday and another on its heels for Friday. Thursday’s system passes with little fanfare. There is a slight chance of light precipitation for the mountains and north and a breezy wake everywhere as the northwest wind picks up and gusts to 20-30 mph in the afternoon. A weak surface high moves in behind the clipper, settling the breeze overnight and bringing a cooler start to Friday. Friday sees the breeze picking up again as the next clipper approaches the region. This system appears to have a bit more spice with it and could bring some squally convective showers that may produce graupel (soft hail) along with rain showers along with the risk of a clap of loud thunder ahead of the front, with snow showers on the backside. While the main idea is for this activity to occur over the mountains and northward along the Quebec border, all areas run the risk of receiving a little something out of this boundary as it passes through. Wind gusts in the 30-40 mph range are possible Friday afternoon and continue overnight into Saturday and may bring some isolated power outages. Saturday's wind speeds gradually diminish during the day as a Canadian surface high moves into the region. Sunday morning, most areas fall below freezing, starting the day cold. Clouds increase later in the day, ahead of the next system on Monday. At this point, the operational model ideas aren’t that bullish on precipitation late Sunday night into Monday, but anytime there is an upper low over the southwest, forecast models struggle with solutions downstream. As the energy associated with it moves to the northeast over the next couple of days, some clarity will come. The kicker energy is currently south of Alaska as of Thursday morning, which is the other key ingredient in what happens. The feature may produce snow in the north and rain showers in the south, but it’s too early to get into details on how much precipitation and what type comes out of it. Needless to say, I am rather curious to see if a surprise may come out of it.   Always have MULTIPLE ways to receive weather alerts.
