Parts of the East and the South can expect some rainy conditions with the threat of thunderstorms over the next couple of days. This is due to an upper-level disturbance that is combining with warmer and more humid air that is present this June. This is typical weather of June, and this type of weather is to be expected during this month. After the first cell of thunderstorms has moved out of the United States, a second disturbance will shift into the northern Rockies and Northern Plains, triggering even more thunderstorms and rainy weather throughout the rest of the week. The main concern with these systems is strong, damaging straight-line winds and hail. Flash flooding is also possible.
Over the course of Tuesday, the lower Mississippi Valley, Tennessee Valley, Ohio Valley, and parts of the Northern Gulf Coast will experience thunderstorms and a chance of possible flash flooding. Winds will be the biggest threat for this system, yet the chance of tornadoes occurring cannot be ruled out just yet. As for the southeast and Mid-Atlantic states, residents can expect patches of damaging winds and large hail, but this will be limited to the afternoon and early evening hours. The Northern High Plains are expected to see extremely high winds, large hail, and tornadoes have the possibility to form if the conditions permit. The states of Wyoming, Montana, and the Dakota’s are most likely to experience the worst of the upper-level disturbance this week.
On Wednesday and Thursday, the eastern region will see scattered to a plentiful amount of thunderstorms. This will occur from Florida to the Northeast. A few of these small systems have the possibility to turn severe for just a short period of time. Moving on to the Midwest, a few severe thunderstorms will move along an advancing cold front from the Northern Plains and Western Great Lakes, then making its way into the Mississippi Valley and the Plains of Eastern Colorado, Kansas, and Oklahoma. The biggest concern for this system is damaging winds and hail, as it is for the most of these cells present this week in the forecast.
It is not unlikely during this time of year that the atmosphere is loaded with moisture in many areas around the States. In turn, this means that thunderstorms can make themselves present in the form of heavy downpours, instead of light showers and miniscule thunderstorms. Through Tuesday evening, there is a chance of spotty flash flooding in parts of Louisiana, Mississippi, Tennessee, Alabama, east Texas, and even up through the Ohio Valley. In the Northeast, there is a still a small chance of flash flooding throughout the urban areas due to a slow-moving system over the major cities along with I-95 corridor. This occurred on Monday in Newark and the small suburbs of Philadelphia. Even though there is a small risk of flooding present, it is does not mean that there is a widespread risk of flooding.
Spotty flash flooding in the East is a possibility on Wednesday due to the slow-moving thunderstorm systems. Also, there may be a potential for thunderstorms to begin clustering and forming overnight in parts of Kansas and Oklahoma. This could be the trigger that starts flash flooding overnight Wednesday into Thursday morning.
