The first of two cold fronts this week will be responsible for much nicer weather over the course of the next few days across the Eastern U.S. This first front is moving off the East Coast this Monday while stalling off near the Gulf Coast. Then the second front will work in from the north by midweek.
This Monday, while New England deals with rain and a few thunderstorms develop over Florida, the remainder of the Eastern US will be dry and beautiful, featuring mainly sunny skies. Humidity will be at very comfortable levels with dew points down into the 50s and 60s, which indicates a comfortable air mass for this time of the year. High temperatures will be up to 10 degrees below average in the Northeast, and even cooler than that in New England, but remain seasonable across the rest of the region. Actual highs will generally be in the 70s and 80s. It will soar into the 90s along the Gulf Coast and into Florida. According to Brian McNoldy, a meteorologist from Miami, “Through the start of June, Miami has had 3 days with highs ≥90°F (the average is 8.6 by now). The streak of cooler weather is about to come crashing down; could break 90° mark every day for at least the next five days.”
Tuesday will be quite seasonable. Temperatures will still be well below average in the Northeast, meaning that highs will be in the 50s, 60s, and 70s while it’s near-average in the Southeast and Ohio Valley into the 80s and 90s. A second low pressure associated with the secondary frontal passage will bring in a couple rounds of rain showers to the Ohio River Valley into the Northeast and Mid-Atlantic. Otherwise, a blend of sun, clouds, and dry conditions will be present across most of the East. A few thunderstorms may be possible near the Gulf Coast and in Florida along that stalled-out front, but it won’t be like the wet pattern from last week.
On Wednesday, the cooler-than-normal temperatures will persist across the Northeast with highs generally 5 to 15 degrees below normal. Places across the rest of the Eastern U.S. will experience high temperatures a few degrees above average. A refreshing air mass will become reinforced across the Northeast, Mid-Atlantic, and Ohio Valley behind the cold front passing through while it will feel a bit humid in the Southeast. Unfortunately, the cold front will stall out over the Southeast, preventing a decrease in dew points from occurring. Yet again, a few thunderstorms will be possible near the Southeast coasts, and there may also be a few spotty showers that develop in the Northeast. Dry and sunny conditions will remain the story overall, however.
The cool air will finally erode across the Northeast as warmer air begins to creep in from the south thanks to a wind shift. Now while seasonable temperatures are affecting the northeastern U.S., warmer conditions will seep into the Ohio River Valley and Southeast from the west, leading to warmer weather. That will translate to highs mainly in the 80s and 90s. The Northeast will be gorgeous with sunshine and high temperatures in the 70s, making for a perfect day for early-June. The typical, summertime storms will remain present near the Gulf Coast all week long.
By Friday, temperatures will be above average across the large majority of the Eastern U.S. with highs in the 70s, 80s, and 90s. It will also be the driest day with a few spotty storms possible, mainly in the Southeast. A new disturbance that will approach the Great Lakes late in the day may also spark an isolated thunderstorm or two in the Ohio River Valley. The main story though will be the gorgeous, dry weather, featuring mostly sunny or partly cloudy skies paired with relatively-low dew points into the 50s and 60s.
