4 Things to Watch in This Week's Weather

Published: June 11, 2017

The central and eastern U.S. will start this week with a taste of summer, but it will feel more like winter in parts of the West.

This pattern will not last long. By late week or next weekend, the Midwest and Northeast will begin to see temperatures moderate, and a warm-up is in store for the West.

In addition to the temperature changes, severe thunderstorms may impact portions of the Plains and upper Midwest this week, and wet and stormy conditions will prevail across parts of the South.

1) Heat Wave in Midwest, Northeast

An upper-level ridge of high pressure, or northward bulge of the jet stream, will build across the central and eastern U.S. early this week. This will allow a more southerly flow to develop, bringing hot and humid conditions into much of the Midwest and Northeast.

Daily record-high temperatures are also expected in the East early this week.

The result will be several days of temperatures in the 90s and dew points in the 60s, making it feel humid and even hotter than the reading on the thermometer. Highs will be 10 to 25 degrees warmer than average into midweek in the Midwest and Northeast. The most persistent heat will be in the Midwest.

Low temperatures will also be above average, with lows only dipping into the 70s for many locations.


Midweek Forecast

Changes will begin to be felt in parts of the Northeast Wednesday and Thursday as a backdoor cold front will slide southward across the region. This will allow temperatures to return to near average.

Another cold front will push into the Plains midweek, also allowing temperatures to moderate. This cold front will slowly push eastward late week and will bring cooler conditions to the Midwest by next weekend.

2) Severe Thunderstorms May Develop

A stationary front brought severe thunderstorms on Sunday from South Dakota and Nebraska northeastward into northern Michigan.

Monday and Tuesday, a strong area of low pressure is expected to move into the Plains. Ahead of this system, the warm temperatures and humid conditions will be in place.

Strong winds in the upper levels of the atmosphere, combined with ample moisture and the eastward tracking cold front, will result in enough instability to likely produce severe thunderstorms.

Severe Thunderstorm Setup

On Monday, the highest risk of severe storms will be from eastern Montana and eastern Wyoming into northern Nebraska and the Dakotas. The area of concern will slide eastward on Tuesday, likely stretching from eastern North Dakota and Minnesota southward into western Iowa, eastern Nebraska, central Kansas and the Texas and Oklahoma panhandles.

Damaging wind gusts, large hail and a few tornadoes are concerns early this week with any severe thunderstorms that fire up.

A few strong to severe thunderstorms are also possible mid-to-late week as this system pushes eastward, but the details are uncertain at this time.

3) Heating Up Again in Parts of the West

The week will begin with a strong upper-level trough, or southward dip in the jet stream, over the Northwest. The result will be rain and higher-elevation snow, along with chilly conditions for mid-June.

High temperatures will be 10 to 25 degrees colder than average early this week across the West. Highs will only top out in the 50s and 60s for much of the Pacific Northwest and Great Basin, with 70s and 80s from Southern California into Las Vegas.


This Week's Forecast

This trough will slowly lift out of the region midweek. By next weekend, an upper-level ridge of high pressure will begin to build over the West.

The result will be a return to drier conditions throughout the West, with the possible exception of western Washington and northwestern Oregon.

In addition, temperatures will rise through mid-to-late week. Above-average temperatures are expected from California into the Great Basin and Southwest by Friday, and this increase in temperature is expected to prevail into next weekend.

Highs will soar into the triple digits for the Desert Southwest, with 80s in much of the interior West. This pattern may result in a significant heat wave in parts of California and the Southwest.

4) Wet, Stormy Week in the South

High pressure brought mainly dry conditions across the South through the weekend, with the exception of Florida and the northern Gulf Coast which saw a few scattered showers and thunderstorms.

This area of high pressure will begin to weaken early this week as it slides eastward. A southerly flow will prevail across the region and tropical moisture will increase, resulting in a return to wet weather.


Late-Week Forecast

Showers and thunderstorms will begin to spread across much of the lower Mississippi Valley and into parts of the Southeast early this week.

By midweek, a cold front will push into the southern Plains, bringing a few thunderstorms there, as well. This boundary may stall and could bring repeated rounds of rain to portions of the region.

The risk of showers and storms will also persist into late week for much of the South in areas east of the Mississippi River.

There will be plenty of moisture in the region, which may enhance rainfall and bring the risk of flash flooding. The good news is that, although a wet pattern is expected, we are not anticipating the heavy rainfall that occurred in Florida last week.

The cloud cover and thunderstorms will help to keep temperatures near to slightly below average across the region through this week.

At least 254 people were killed in the in the city of Mocoa (population 40,000) in southwest Colombia near the border of Ecuador early Saturday, when torrential rains triggered a debris flow on a nearby mountain that surged into the town as a huge wall of water carrying tons of mud and debris.

Iconic American Destination Virtually Isolated for Rest of Year

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

Why the Arrest of a Science-Loving 14-year-old Matters

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
