The summer season is upon us, and probabilities are quite high that overall temperatures in the Arctic region will be at or below normal if long-term trends hold true. In fact, temperatures in the Arctic region during the first half of June are at historically low levels when compared to any year back to 1958 which is when data records began for this area. Interestingly, water temperatures in portions of the Atlantic Ocean have cooled off quite noticeably during the past year or so and cooler-than-normal water in the Main Development Region of the tropical Atlantic can have an inhibiting effect on tropical activity. Perhaps this change in water temperatures in the Atlantic Ocean and the drastic start to the summer season with respect to temperatures in the Arctic is signaling an upcoming change in the Atlantic Multidecadal Oscillation (AMO) which has been in a “positive” phase since the middle 1990’s.
“Normal” temperatures in the Arctic region during the summer season are right around the 32 degree (F) freezing mark and as long as temperatures average at or below normal, additional melting of Arctic sea ice will have its limitations. Meanwhile, the other nine months of the year in the Arctic region have consistently featured above normal temperatures in recent years. One possible explanation of this persistent temperature pattern in the Arctic region featuring nearly normal to below-normal summertime conditions and warmer-than-normal weather during the coldest nine months of the year is increased levels of water vapor in the atmosphere.

After a couple of very comfortable days in the Mid-Atlantic region, changes will take place here at mid-week with warmer and more humid conditions on the way. The atmosphere will also become more unstable later today as an upper-level low expands into the northeastern states bringing us scattered PM showers and thunderstorms. On Thursday, an incoming frontal system will generate more instability in the atmosphere and there can be another round of PM showers and thunderstorms...some of those late day storms on Thursday can be strong-to-severe. From this vantage point, the passage of the late week frontal system looks like it’ll set us up for a pretty decent weekend in the Mid-Atlantic region.

The weather will remain quite comfortable for another day in the Mid-Atlantic region with high pressure still in control, but changes take place at mid-week. On Wednesday, an upper-level trough of low pressure over the center of the country will expand into the northeastern states and the weather will become warmer, more humid, and more unsettled with the chance of PM showers and thunderstorms. On Thursday, an incoming frontal system will add fuel to the fire and there can be another round of PM showers and thunderstorms in the Mid-Atlantic region...some of those late day storms on Thursday can be strong-to-severe. From this vantage point, the passage of the late week frontal system looks like it’ll set us up for a nice Friday, Saturday and Sunday in the Mid-Atlantic region.

The weather turns warmer today with afternoon highs not far from 90 degrees, but mid-week will bring the hottest weather of the week. Temperatures on Wednesday afternoon could peak in the upper 90’s to go along with sunny, dry and breezy conditions increasing wildfire concerns. The weather is likely to become more unsettled again during the upcoming weekend with an increasing shot at showers and thunderstorms.
