2017 Tropical Season Outlook Webinar

Risk for Thunderstorms across Portions of the Northern Plains on Monday
Isolated thunderstorms are expected to develop across the Northern Plains this afternoon and evening as a warm front and area of low pressure moves across southern Canada. While significant impacts are not anticipated, some of the stronger storms could post a low threat of severe winds and hail before dark.

Region 1 Monday, July 24, 2017Region 1

Thunderstorm Potential Monday for the Mid Atlantic and Northeast
Thunderstorms may develop across portions of the Mid Atlantic and Northeast as an upper level trough pushes through the region. The bulk of the current morning shower and thunderstorm activity will gradually clear out by midday with redevelopment or reintensification of activity expected later this afternoon. A few storms could pose a low threat of marginally severe wind and hail before dark.

Update 2:30pm EDT: Showers and thunderstorms developing across New York and Pennsylvania ahead of a front.

Thunderstorms for the Tennessee Valley on Monday
A weak area of low pressure is forecast to advance toward the Tennessee Valley during the afternoon and evening hours on Monday. This should result in at least widely scattered showers and thunderstorms. While significant impacts are not expected, a few of the stronger storms may pose a low risk for marginally severe wind.

Excessive Rainfall Continues Monday for the Southwest and Intermountain West
As monsoon moisture overspreads much of the Southwest US northward to the Intermountain West, scattered showers and thunderstorms will develop once again today across the region. While not all areas will receive rain, rainfall amounts will range from 0.25-1 inch, with locally higher amounts in excess of 1.50 inches.

Risk for Excessive Rainfall along the Gulf Coast Monday
Scattered showers and thunderstorms are already occurring across portions of the Gulf Coast this morning and will likely continue to develop over the region through the late afternoon or early evening hours.

Strong to Severe Thunderstorms Tuesday across the Northern Plains and Upper Midwest
As an area of low pressure intensifies over Canada, instability will build ahead of a cold front. Scattered thunderstorms are anticipated across much of the Northern Plains by the afternoon hours, eventually congealing into one or more organized complexes by the late evening as they approach the Upper Midwest. Large hail, damaging winds, and tornadoes will all be possible with these storms. Later in the evening, thunderstorms will transition to a damaging wind threat. In addition, there will be a risk for excessive rainfall. Rainfall amounts could range from 1-2 inches with locally higher amounts in excess of 2.50 inches.

Excessive Rainfall Continues for the Intermountain West on Tuesday
As monsoonal moisture shifts slightly northward, scattered showers and perhaps a few thunderstorms are anticipated across the Intermountain West. For areas that receive precipitation, there will be a risk for excessive rainfall. General amounts of 0.25-0.75 with locally higher amounts in excess of an inch are expected.

Potential for Thunderstorms across the Midwest on Wednesday
The risk for thunderstorms will shift slightly southeastward and impact much of the Midwest on Wednesday. As a cold front slowly moves southeastward into the region, increasing instability ahead of the front will likely lead to scattered thunderstorm development. Thunderstorms, potentially strong or severe, may be ongoing early in the day across the Upper Midwest, with additional development likely throughout the day across the remainder of the region. Large hail and damaging winds will be the primary hazards with these storms, though an isolated tornado or two cannot be ruled out with the stronger storms. In addition to the severe threat, excessive rainfall may occur, generally centered around the Iowa/Illinois border.

As deep moisture spreads over the region and a cold front moves in from the north, shower and thunderstorm development can be expected across portions of Colorado and New Mexico on Wednesday. There may be a risk for excessive rainfall across the region. Rainfall amounts could range 0.50-1.00 inch with locally higher amounts in excess of 1.25 inches.
