Before I get into it, I am tweaking the PTW Weather Wall page. NWS is changing its graphical formats, which will bring improvements. The snowfall and ice map graphics have been adjusted, as I noticed they were not updating. If you are looking for Maine-related weather information, there is no other source like it. It is the most popular page on the site, aside from the discussions. This site is a one-stop source in the sea of weather information. Also, I am juggling things here. I am bored with this pattern, so I am trying out different graphics and presentations. Feedback appreciated! High pressure rules ThursdayA relatively strong area of high pressure rides overhead of the region. The breeze of the past few days subsides for the most part. A mainly sunny sky is expected for the day, with temps on the cool side, with highs in the mid-30s for the north and mountains to the mid-40s for the coast. It will be another night of chilly temperatures, but not quite as cool as the Thursday morning start, with teens over the interior and 20s for the shorelines. Looking at the 500mb steering level, the clipper on the way is beginning to show the dig, and the surface map shows the cold front out ahead of it. High pressure over the region slides east on Friday, and the clipper arrives Friday night. Lets get a bit technicalI know horizontal forecast charts are popular and easy to pass along, but they don't show the atmosphere as intended. The vertical view, as in this BUFKIT sounding profile, shows everything that is going on. Looking at this, it shows just how weak a system this is. A lot of dry air aloft is indicated by the distance between the red temperature and green dew point lines. It narrows up below 1,000 feet, but that is like squeezing juice out of a wet rock. I removed the SKEW from this image to better show the warm nose, since it is fractional. For the sharp observer, the cold air dam sits just below it. A bit of light ice is possible in the wee hours of Saturday morning over the north, but not enough to cause travel issues. This is a nothingburger. The wind will pick up on Saturday as what energy is left from this combines with a storm well offshore, which combines and intensifies on its way out in the Atlantic. Pardon me if you have seen this movie hundreds of times in the past 19 months. I may be exaggerating a bit, but it has been many moons since the area has seen a storm of precipitation significance, and the water table is proving it. The next system to watch appears mid next week, on Wednesday, into Thanksgiving. It looks like rain for now, with perhaps light snow in the far north, but with an upper low passing over the southwest part of the country, I give models little to no credibility in the long range until that clears out. Stay tuned! Ski season starts Friday... are you ready?The PTW Weather Wall updates 24/7Your financial support keeps the lighthouse lit |
