The remains of Irma will contribute to another couple of unsettled days around here, but the weekend is looking quite decent for mid-September. Weak high pressure will build into the region this weekend and it’ll be quite warm on both Saturday and Sunday with some sunshine on each day. Hurricane Jose continues to churn slowly out over the Atlantic Ocean and it’ll be monitored over the next several days as it may eventually head towards the US east coast. In addition, there are other tropical systems behind Jose in the eastern Atlantic which will also have to be closely monitored in coming days.

The remains of Irma will bring us the chance for showers and thunderstorms for the next couple of days, but it does not look like a heavy rain event. Weak high pressure will build into the region this weekend and it’ll be quite warm on both Saturday and Sunday. Hurricane Jose continues to churn well out over the Atlantic and it’ll be monitored over the next several days, but is unlikely to ever impact the region.

The remains of Irma will bring us the chance for showers by later today and that threat will continue into the late week as the system stalls out as it gradually dissipates. It’ll turn slightly warmer as the week progresses and the overall cool pattern of the first ten days of September will evolve into a warmer pattern relative-to-normal as we head towards the second half of the month. Meanwhile, Hurricane Jose will take an erratic pattern over the few days over the western Atlantic and then it should take a more consistent path to the northwest and towards the US east coast. We may to deal with Jose as a threat in the Mid-Atlantic region somewhere by the middle or latter part of next week.

Our nice weather pattern will continue as we begin the new work week with high pressure still in control in the Mid-Atlantic region. The much weakened remains of Irma will lift northwestward over the next 24 hours into the Tennessee Valley and they could generate some shower activity in the NYC metro region from tomorrow night into Wednesday.

Irma continues to track west-northwest as a major hurricane - now at category 4 status - and is likely to maintain much of its strength over the next couple of days as it moves over very warm waters. Irma should move to a position quite close to the southeastern coast of Florida by early Sunday and then it is likely to turn northward as deep upper-level troughing digs in over the Northeast US. This likely path will result in virtually the entire state of Florida experiencing hurricane conditions later this weekend and into early Monday as the hurricane crosses from south-to-north roughly over the center of Florida. At landfall, Irma is likely to have category 4 status, but category 5 status is not out of the realm of possibility. By the time Irma reaches the central and northern parts of Florida, it is likely to have weakened some to perhaps category 2 level. If there is any impact from the much-weakened remains of Irma in the Mid-Atlantic region, it would likely be in the Tuesday/Wednesday time period.

High pressure will build into the region later today and we’ll have another stretch of nice weather in the Mid-Atlantic region. Meanwhile, Hurricane Irma continues on a WNW track as a category 5 “major” hurricane. The hurricane is being steered by a subtropical ridge to the north and this motion should continue for the next 48 hours or so. After that, an upper-level trough will dig into the eastern US and allow Irma to turn northward. There is still some uncertainty about the timing of this turn northward, but major impact is very likely across southern Florida over the weekend as it makes its turn. There may be some impact around here around Tuesday of next week from a much weakened tropical system.

A strong cold front passed through the region last night and it’ll be noticeably cooler today while low pressure rides along the stalled out frontal boundary zone. As a result, the threat for rain will continue through the day and into tonight and there may be a thunderstorm or two mixed in. Meanwhile, major Hurricane Irma continues to grind westward over the Atlantic and is on a track that will bring a significant impact to southern Florida later in the weekend.

A strong cold front will head towards the east coast later today and bring some shower and thunderstorm activity to the region. This front will then stall along the coastline later tonight and low pressure will ride up along the frontal boundary zone on Wednesday. As a result, the threat for rain and possible thunderstorms will continue tomorrow and some of the rain can be heavy at times between late this afternoon and tomorrow night. Ahead of the front, temperatures will climb into the 80’s today, but will be confined to the 60’s on Wednesday with the clouds and rain. Meanwhile, Irma continues to churn over the Atlantic now as a category 5 “major” hurricane and is currently on a westerly track. It is looking increasingly likely that Hurricane Irma could have a significant impact on southern Florida by late in the upcoming weekend.

A cold front passed the region last night and has ushered in an unseasonably cool air mass for the beginning of September. High temperatures today and Saturday will be confined to the 60’s in most areas – well-below normal for this time of year. In addition to the chill, moisture from the remnants of Harvey will push to the northeast and interact with an upper-level trough of low pressure. The result will be some rainfall for the Mid-Atlantic region on Saturday and perhaps into early Sunday. Overall weather conditions should improve noticeably by the early part of next week. Elsewhere, the tropics remain quite active and Hurricane Irma will track in a general westward motion in coming days. Irma may very well become a concern for somewhere in the US in about ten days or so - stay tuned.

A cold front will approach the region late today and bring us the chance for some scattered showers and thunderstorms. Following the frontal passage, an unseasonably cool air mass for late August will envelope the Mid-Atlantic region and temperatures will be well below normal as we end the work week and begin the weekend. At the same time, moisture from the remnants of Harvey will push to the northeast and the result is likely to be some shower activity around here on Saturday. Overall weather conditions should improve early next week.
