A very active but unfortunately unpleasant week is in store for millions across the country as round after round of storms impact the eastern two-thirds of the nation. We’re tracking that and more in this week’s 5 Things to Watch.

Rounds of Storms for East:

A broad trough over the East this week will instigate the development of multiple low pressure systems, making for wet and stormy weather. For the start of the week, there will be a broad area of low pressure over the Mid-Atlantic and a more-organized low over the Ohio River Valley. Both of these storms will pose a risk for severe weather across these regions. Damaging winds and large hail will be the main risks, but isolated tornadoes cannot be ruled out. That second storm will track into the Northeast by Wednesday while that first one exits offshore. Meanwhile back to the west, a new storm will begin to organize over the central Plains, bringing scattered showers and storms, some of which will be severe. That storm will track toward the East Coast late-week, exiting offshore by Friday. A ridge will then build over the East, allowing for warmer temperatures and slightly drier conditions for some, especially at the East Coast.

Eastern Flood Threat:

This spring has definitely been known for the rain across much of the East this year. Record rainfall has been felt across numerous cities, resulting in overflowing rivers and flooded communities — and the rain just won’t end. The Mississippi and Arkansas are a couple major rivers that have been problematic the past several weeks, with many stations reporting either moderate or major flooding. The additional rainfall, which may amount to half a foot of rain this week, will only make the flooding conditions even worse.

Mid-Atlantic Severe:

Severe weather will be possible both Monday and Tuesday across the Mid-Atlantic. We are not expecting an outbreak of severe weather, but we still expect severe storms to turn severe during the afternoons and evenings. Showers near the Appalachian Mountains Monday morning will move east, strengthening into thunderstorms for the latter half of the day. Once they near the I-95 corridor, some of them may intensify into severe storms, posing the risk for damaging winds and small hail.

Below Average Temperatures Dominate:

As toughing, or dips in the jet stream, dominate the weather pattern across most of the Lower 48 of the US, this will lead to below normal temperatures for many locations. Widespread high temperatures of 5-15 degrees cooler than average are forecast this week, translating to actual highs generally in the 70s, 80s, and 90s. The only exception to the cool temperatures relative to average is the West Coast early-week and Texas and the central East Coast. Looking ahead to late-June, we do anticipate temperatures to warm to above average conditions across the eastern and southern US, however.

Quiet in the Tropics — For Now:

It’s quiet in the tropics — for now. We are currently through the first half of the first month of the Atlantic hurricane season with only one named so far, which is typical at this point in time of the season. Looking ahead this week, no activity is expected in the tropics. August and September are the most active time of hurricane season climatologically. According to the National Oceanic and Atmospheric Administration, a near-average hurricane season is expected.
