DAYS 1-5 (JULY 21-25)<\/p>\n\n\n\n
Today, we still have the smoke in the atmosphere, both upper and lower, fairly high humidity, and a thunderstorm threat (for parts of the region). Tomorrow, we lose all of it and gain one of the nicest days of the summer. To get there, we have to go through a transition today as a disturbance moves across the region. Previous chatter was a little more inclusive of the entire region in a significant thunderstorm threat, but one must keep in mind that weather in the hours just before can impact weather in the hours just after, and if using short range models for guidance, it’s essential to watch trends on those as well as keeping track of what’s going on via surface obs. Last night, some of the convection from yesterday’s activity to the west survived its trip east, even a bit more so than I expected it to, and one thing this has done is to stabilize the atmosphere in a good part of the region north of I-90, and it is these areas that have the smaller risk of showers and storms today, just some isolated activity popping up early or mid afternoon. To the south, closer to where today’s disturbance will pass, and with less stable air, look for a little more in the way of shower and thunderstorm activity developing and moving in during the afternoon and into the evening. It is still quite possible that a few of these storms may become severe with damaging wind being the most significant threat, but also some chance of larger hail as well. All of this activity moves away later tonight and is replaced by a dry air mass from Canada. Even though a lot of our wild fire smoke has originated in Canada, the shift in the winds both surface and aloft will be enough to remove most of the smoke from our region, and Thursday should feature a deeper blue sky than we have seen in quite a while, not that we’ve seen much of any blue sky this month anyway. You may be wondering if this is temporary and we’re going right back to the pattern we’ve been in. Actually, not this time. The pattern is changing for now, and even though a disturbance has to swing through the region on Friday with some clouds and the threat of passing showers, we’ll be introduce to fresh Canadian air, part 2, on Saturday. But things are moving along and the next disturbance will be on the way by Sunday, once again with more cloudiness and the threat of some shower activity. The difference now is that we’re not seeing these frontal systems move in then sit around for a few days, creating stretches of unsettled weather…<\/p>\n\n\n\n

DAYS 6-10 (JULY 26-30)<\/p>\n\n\n\n
A westerly air flow pattern will feature drier than average conditions and near to below normal temperatures, often seeing air coming from Canada. Best chance for an interrupting disturbance with showers mid period.<\/p>\n\n\n\n
DAYS 11-15 (JULY 31 \u2013 AUGUST 4)<\/p>\n\n\n\n
Overall pattern keeps us in a west to northwesterly air flow, with no major heat, temperatures near to slightly below normal, and a drier overall regime with fewer shower chances.<\/p>\n","protected":false},"excerpt":{"rendered":"
