Temperatures rise from Midwest to Northeast ahead of late week coastal storm – AccuWeather.com/ar/

AccuWeather meteorologists say the record-challenging warmth sweeping across the Midwest will extend across the Northeast this week. November’s warm weather could provide ideal conditions for early vacation travelers for their flights before a rainstorm that will extend from the south to the East Coast late this week.

Midwest: Above-average highs, record-challenging locations

Temperatures will trend into the 60s and 70s F across much of the Plains and Midwest during the first half of this week. Even along the northern tier of the Midwest, there are highs in the 50s.

“Across most of the central U.S., highs will be 10 to 20 degrees higher than the historical average,” AccuWeather Senior Meteorologist Brett Anderson said.

Increased winds from the southwest will help bring in warmer air and lead to other issues such as higher fire danger in the dry zone. Not to mention, a stiff breeze can cause some headaches and make cleaning the leaves a challenge.

A change in winds behind the weather feature will also be responsible for reducing the unusual warmth.

“A cold front will put an end to this warm spell by Thursday over parts of the northern Plains and Friday across much of the Midwest,” Anderson said.

Northeast: Late week warm-up before coastal storm

Farther to the east, a decrease in the jet stream will allow cold air to push southeastward into Canada before significant warming occurs in the latter part of the week.

This cold flow will help keep most areas a few degrees away from the historical average through the middle of the week. Daily highs will range from the mid 30s in northern Maine to the upper 50s in southeastern Virginia.

An area of ​​high pressure, which has been the cause of unusually cold nights across the Northeast, will finally shift off the coast starting around midweek, according to Anderson.

Temperatures will trend higher starting Wednesday along the western slopes of the Appalachian Mountains and around the eastern Great Lakes region. On Thursday, the warm-up will advance through the Appalachian Mountains and up the Interstate 95 corridor and the East Coast.

On Thursday and Friday, highs will be in the lower 60s in New York City. In Philadelphia, Baltimore and Washington, D.C., highs will be in the 60s. By Friday, temperatures are expected to reach the high 60s in Boston and rise into the 50s in coastal Maine and along the northern tier of New England.

“At this level, highs across much of the Northeast will be 10 to 15 degrees above the historical average later this week,” Anderson said.

The region will not be blessed with dry, warm conditions like the Midwest, as the storm sweeping the Gulf Coast will likely reorganize and move north along the East Coast at the end of the week.

The extent of rainfall from the coastal storm late in the week is still up for debate

As the southerly storm redevelops east of Florida late Thursday or Friday, a large mass of tropical moisture will shift northeastward from the Gulf of Mexico and the Caribbean Sea.

“A strong cold front moving eastward by the end of the week will likely pick up the storm and quickly pull it northeast as it strengthens over the warm Gulf Stream waters off the East Coast,” Anderson said.

This does not look like a full tropical system, but more like a hybrid storm, with tropical and non-tropical characteristics.

The speed at which the front merges with the storm will likely determine how close the storm’s track will be to the East Coast, how heavy rainfall will be and how far it will spread inland.

At this point, the storm appears to have the potential to bring a period of heavy rain and gusty winds to central and eastern New England from late Friday night into Saturday night.

“Farther west Friday into Saturday, there will be a second area of ​​rain or showers over the interior northeast associated with the cold front in the Midwest as it heads toward the Atlantic coast,” Anderson said.

Temperatures will drop in areas that capture rainfall along the coast and inland from both systems on Thursday. Areas where rain stops for a period before the cold front, especially near the coast, will see peak temperatures on Friday and Saturday.

For those who enjoy the warmer weather in November, a change in style can provide a reality check. The country is likely to see a period of very cold weather this weekend and into early next week, with some lake-like snow likely in parts of the interior. This will occur as the jet stream declines after the cold front and coastal storm leave.
