The video explores how the weather should unfold this weekend and early next week. While longer-range models show cold air building in Canada and moving south later next week, no snow or freezing weather is in the forecast for the Northeast for the next 10 days.
Nadine has been a fixture over various parts of the open Atlantic for weeks now, and it is likely to still be on the map at the start of October.
Note how the satellite coverage ends over the eastern Atlantic. The satellite that had monitored much of the U.S. and Atlantic Ocean malfunctioned earlier this week. The geostationary satellite that had been monitoring the western U.S. and the Pacific was moved east to make up for some of the lost coverage, but you can see the eastern edge of its picture taking ability from its newest location.
A front that will usher in slightly less humid air for the Northeast tomorrow will trigger locally strong thunderstorms today.
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.
