November is off to a cool start for much of the northern-half of the country and more cold weather is in the forecast. Numerical guidance continues to indicate much of central & eastern parts of the country will remain below average through mid-November.
The upper-level pattern will favor cold shots of air from the Arctic down into the United States as the jet stream takes a deep equatorial dive. This big dip in the jet stream will allow the cold air to seep farther south and southeast by late this week week into the weekend. High temperatures will be 10 to 30 degrees below average for the aforementioned areas. A good part of the Southeast will see highs fall into the 40s & 50s with lows in the 30s from Friday through Sunday.
At this time, guidance is indicating another strong push of cold air will dive into central and eastern parts of the country early next week. This airmass looks to be even colder than the late-week surge. It is too early to determine just how cold it will get and where the brunt of the cold air will move but all indications are for a chilly airmass impacting a good part of the country east of the Rockies. It appears the Southeast will see pretty chilly air with highs possibly in the 40s & lows in the 20s.
The Climate Prediction Center indicates much of the eastern and central United States will see high probabilities of below average temperatures for days 6 through 10 and days 8 through 14.
Check back tomorrow for a detailed update from Matthew on the big cool down!
