Only some will see some relief this week from this past sweltering, stormy weekend. For much of the nation, record heat, flooding, and severe weather will remain in the forecast, at least until mid-week. Here’s this week’s 5 Things to Watch:
Drier Weather on its Way for the Northeast:
Since the beginning of last week, most of the Northeast has been dealing with sweltering temperatures near, or above, 90 and drenching storms. After similar weather for the 4th and this past weekend, we should be seeing some drier weather over the next few days. Some showers may creep up from the Mid-Atlantic this afternoon, but after that, the region will be mostly clear until Wednesday. Clearer skies are definitely something to look forward to, but temperatures will likely remain in the mid-to-high 80s. Luckily, drier air will mean less humidity and make the beginning of this week slightly more bearable than the past few days.
Tropical Disturbance to Drench Mid-Atlantic:
The National Hurricane Center has been watching a low pressure tropical disturbance over the Southeast for a few days now. Although it’s not expected to develop into a depression or storm over land, it has the potential to drench the Mid-Atlantic and Southeast over the next few days. Parts of the coast have been placed under a marginal risk for excessive rainfall today and tomorrow as this system slowly begins to organize and move towards the Gulf. Some localized flooding is likely, especially for areas that have received rain over the weekend.
Record Heat in Alaska Continues:
While wildfires during the summer are not all too uncommon for Alaska, 90 degree weather certainly is. Record high temps have been set in the last few days over Anchorage, Bethel, and King Salmon as temperatures soared near and above 90. Due to high temperatures and very dry air, multiple wildfires broke out over the state, introducing widespread air quality and visibility issues due to smoke. Unfortunately, the high pressure in place over Alaska right now isn’t expected to move until later this week, closer to Wednesday. Until then, scorching temperatures and fire weather conditions will continue.
High Plains Severe Threat:
As heat and moisture clash with lift from incoming low pressure systems and frontal boundaries, the High Plains are in for at least 2 more days of severe weather. This afternoon, as a cold front continues to make its way down from Manitoba, our severe weather threat will center around the Dakotas and Central Nebraska. Damaging straight line winds and hail will be the biggest threats in developing storms, but a strengthening low-level jet later in the afternoon could mean an increased risk of tornado development over parts of NE and KS. Tomorrow, severe risk will be slightly lessened, but still present as our low pressure system moves to the east. The threat will be contained to eastern ND and SD, as well as western MN. Again, the biggest threats will remain strong winds and hail, but one or two tornadoes cannot be ruled out.
Rainy Outlook Later this Week for Eastern US:
Slightly cooler temperatures towards the end of the week will also be paired with a good chance for one or two days of rain for the Eastern Third of the US. As our pattern changes mid-week from high to low pressure aloft, our sensible weather will change as well. Our new upper level trough will bring a wave of rain and storms across the East, which will be welcomed by some who have had only oppressive heat. To the south, our tropical development currently over the Southeast will have made its way to the Gulf, where it will begin to cause problems in the form of heavy rain and flooding along the Gulf Coast well into the weekend.
