The 2025 Atlantic Basin tropical season officially gets underway on Sunday, June 1st, and there are signs that the initial threat could come as early as ten days or so from now (i.e., June 8, 9, 10th time frame). A teleconnection index known as the Madden-Julian Oscillation or MJO appears to be foreshadowing the potential of tropical troubles in this time frame as it transitions into a “phase” that is generally quite favorable for activity in the Atlantic Basin. In addition, a second favorable sign may be the evolution of the upper-level pattern of highs and lows across North America which may feature strong ridging over southeastern Canada in about ten days or so. A strong ridge in this part of North America is often favorable this time of year for an “undercutting” tropical system in the southwestern Atlantic, Gulf of America, or Caribbean Sea where sea surface temperatures are generally warmer-than-normal.

It’ll turn warmer today following the unseasonably cool weather conditions on Wednesday and this afternoon’s high temperatures should end up in the low-to-mid 70’s. Skies will be mainly cloudy this morning and then some brightening for the mid-day and afternoon hours. A cold front will cross the region tonight with a few showers possible and then it’ll stall nearby on Friday. Low pressure will then ride up along the stalled-out frontal boundary zone bringing with it more rain and possible thunderstorms to the Mid-Atlantic region from later Friday into Saturday….some of the rain can be heavy and some of the storms can be strong. Another cold front arrives late Saturday sweeping the unsettled pattern away and the overall pattern turns drier and increasingly warm during the early part of next week (which is the beginning of the month of June).

It’ll turn slightly warmer today following the cool weather conditions on Wednesday and this afternoon’s high temperatures should end up in the low-to-mid 70’s. Skies will be mainly cloudy this morning and then some brightening is possible later in the day. A cold front will cross the region tonight with a few showers possible and then it’ll stall nearby on Friday. Low pressure will then ride up along the stalled-out frontal boundary zone bringing with it more rain and possible thunderstorms to the Mid-Atlantic region from later Friday into Saturday….some of the rain can be heavy and some of the storms can be strong.

It’ll turn warmer today following the unseasonably cool weather conditions on Wednesday and this afternoon’s high temperatures should end up in the mid-to-upper 70’s. Skies will be mainly cloudy early this morning and then partly sunny for the mid-day and afternoon hours. A cold front will cross the region tonight with a few showers possible and then it’ll stall nearby on Friday. Low pressure will then ride up along the stalled-out frontal boundary zone bringing with it more rain and possible thunderstorms to the Mid-Atlantic region from later Friday into Saturday….some of the rain can be heavy and some of the storms can be strong. Another cold front arrives late Saturday sweeping the unsettled pattern away and the overall pattern turns drier and increasingly warm during the early part of next week (which is the beginning of the month of June).

It turns warmer during the next few days and the warming trend accelerates by late in the upcoming weekend with upper 80’s possible for afternoon highs. The threat exists for showers and thunderstorms from time-to-time during each of the next few days with mainly rain-free conditions likely this weekend.

Warm and unsettled weather conditions for the next few days across the Tennessee Valley with the chance of showers and thunderstorms from time-to-time. It’ll turn drier and warm this weekend with mainly rain-free conditions on both days and highs at 80 or slightly above.

Low pressure is intensifying near the Mid-Atlantic coastline this morning and it will keep it breezy and quite cool around here through tonight with periods of rain. This system will push away on Thursday, but a cold front will approach and then stall in the area for the late week. There can be a few showers from Thursday into Friday and then a period of steadier (and more beneficial) rain is likely from later Friday into Saturday as low pressure forms along the stalling-out frontal boundary zone. Temperatures will be well below-normal today with an ocean flow of air and will remain slightly below-normal right into the weekend. The pattern looks like it’ll turn warmer and drier as we transition to the beginning of June on Sunday and into early next week.

Recent rain events in the Mid-Atlantic region have helped to alleviate drought conditions that began to develop last fall and more beneficial rainfall is on the way with two storm systems. Clouds will lower and thicken today as high pressure shifts off to the east of here and low pressure pushes into the Ohio Valley. A new low pressure system will form by early tomorrow near the Mid-Atlantic coastline and it will produce periods of rain for the mid-week and quite cool conditions as a low-level ocean flow of air forms in the DC-to-Philly-to-NYC corridor. In fact, temperatures may end up being some twenty degrees below-normal on Wednesday with the influence of the still chilly western Atlantic Ocean. A cold front then pushes through the region on Thursday night with a few showers and stalls in the area on Friday. Another low pressure system will likely ride up along that stalled-out boundary zone potentially bringing another round of soaking and beneficial rainfall to the Mid-Atlantic region from late Friday into Saturday.
