With a big high pressure area over the Northeast, it is the coldest morning so far this autumn. This video shows why it won't stay cold. It also shows that even though it will warm up nicely by midweek, the mildness will not last.
This map shows the pressure pattern and includes temperatures near the cold high pressure area and in the southerly flow that is becoming milder.
This is around the anniversary of the birth of John Montague, the 4th Earl of Sandwich in 1718. Montague invented the sandwich. Of course, we consume the weather the atmosphere can service. But we are just interested in the weather now, salami to explain. It'll be chilly today, with temperatures only in the 40s when people who go out for lunch meat. Next we'll get air came from the nation's breadbasket and milder air will arrive in short order. Some sunshine will be mustard from the Midwest to the East Coast.
Across the Midwest, it will start warming up today, and the Eastern Seaboard will be joining the club and ketchup by Wednesday. But lettuce say tomato we won't be bacon. However, I don't think it'll be so bad that people say the cold cuts. One thing we can say is updates will be made as needed. That's because we're always chicken salad facts, and not just chewing the fat here in the office.
Of course, some people don't like chilly air too munch. Others ignore it. They try to be heroes but things go a rye and then they get sick. Some land in the Mayo clinic. But, will the current cold air stay? Baloney! It's only early November. By midweek, a warm tongue will move in and so the temperature won't stay in the subway. Some people may want that mildness to last for a long time. However, as with any special weather request, get in line and take a number.
Thunderstorms will continue to erupt near the northern edge of the heatwave, enhanced by a series of disturbances rippling along in the upper air flow. This is the NWS Storm Prediction Center's severe thunderstorm outlook for today
... the main upper air steering current moves eastward across the northern Plains, then dives southeastward toward the Middle Atlantic states. The core of this current defines the rim of the hottest weather and serves as a conduit for clusters of thunderstorms.
3. Hot air will be moving east from the Plains, reaching the major East Coast cities Friday and Saturday. This map shows the upper-air flow that will make this happen.
This map shows lightning strikes from 8 a.m. EDT yesterday until 7:20 a.m. EDT today. A concentration of thunderstorms can be seen in the Midwest ahead of the cold front.
At 10 a.m., it was already 85 in Boston and 90 in Newark, N.J. The afternoon will be quite hot as weak cold front approaches. It should become a <u>little</u> more more comfortable this weekend.
Subtle and sometimes hard-to-detect boundaries within the heated air mass help with shower and thunderstorm development and organization. There is no one well-defined cold front.
