DAYS 1-5 (MAY 15-19)<\/p>\n\n\n\n
I hope you enjoyed yesterday’s summer preview with lots of sun and warm temperatures. Of course some coastal areas were cooler, as would be expected where wind came off water at this time of year, but even those areas were considerably warmer than during the many days of easterly air flow last week, so they did not completely lose out. During last night, the low pressure that was part of that blocking pattern, in the process of the pattern’s break-down, finally made its way north northeastward and up into southern New England, and will complete its journey across our region today. What this does to us is make our air flow a little more southerly, and with that and more cloudiness today we’ll see temperatures a few to several degrees cooler than yesterday, with 80+ the exception instead of the rule. While this happens though, the dew point will still be on the higher side, around 60, so you’ll still notice that higher humidity. The shower activity with the arrival of the low pressure area has exited the region, but with the air somewhat unstable both today and this evening we can see some pop up showers and even an isolated thunderstorm in a few locations. but the coverage on these will be fairly low, so not everybody will see them, and areas that do will not be impacted for long. This brings us to tonight’s total lunar eclipse. This is a long-duration eclipse, starting just after 9:30 p.m. tonight and ending just before 3:00 a.m. Monday. The WHW area will experience totality from around 11:30 p.m. Sunday to about 1:00 a.m. Monday, with a peak totality at 12:11 a.m. … but will we see it? We’re not going to have a 100% clear sky. We’ll be contending with a variable amount of cloud cover, but what may help is that a little bit of drying will take place as that low pressure area will be north of us, and the wind will have shifted a little more to the west. Some of the short range guidance which simulates the cloud cover is showing some pretty decent gaps in the cloud coverage, which if true could allow many of us to at least get periodic unobstructed viewing of the event. The long-duration of the event also increases the odds. Fingers crossed! Back to the weather. We’re not done with our warm\/humid summer preview yet as we get to Monday, as we’ll be in the air mass ahead of an approaching cold front. As is typical for this time of year, while the front brings the threat of showers and thunderstorms, some of the storms potentially severe, the greatest severe threat will be mainly west of the WHW forecast area as our area will have a stabilizing influence from a southerly wind off the still cool water to the south. However we should be on the lookout for at least the chance of passing downpours \/ t-storms with possible gusty wind as we get into late Monday afternoon and evening. Once that front goes by, that threat ends, and dew point drops, and the temperatures does as well, but modestly. Tuesday will be a “cooler” day but still quite nice with many areas reaching or exceeding 70. However there will be a pool of colder air above and a surface trough that has to swing through the region from west to east during the afternoon hours, and this could trigger the development of showers and even a few thunderstorms, even with some hail potential due to the colder air above us. If this takes place it would be a fairly short-lived event for any given location. Canadian high pressure approaches the region on Wednesday with fair, breezy, and seasonably cool weather, and then the high moves right over us on Thursday which in terms of sunshine and comfortable air is going to likely end up as the pick of the week, unless you like it warmer to hotter. More to come in the DAYS 6-10 section about that. First, the details for the next 5…<\/p>\n\n\n\n
TODAY: Lots of clouds, intervals of sun, and a slight chance of a passing shower or isolated thunderstorm especially during the afternoon hours. Highs 68-75 coastal plain, coolest South Coast, and 75-82 over inland areas. Humid – dew point near 60. Wind S 5-15 MPH.<\/p>\n\n\n\n

DAYS 6-10 (MAY 20-24)<\/p>\n\n\n\n
High pressure ridging building over the region including surface high pressure to the south means fair weather and a significant warm-up May 20-22 including the first chance of 90+ temperatures some areas on the May 21-22 weekend. Later in the period watching for a frontal boundary slipping down from the north and a wave of low pressure bringing a fairly rare rain chance.<\/p>\n\n\n\n
DAYS 11-15 (MAY 25-29)<\/p>\n\n\n\n
A couple shower threats exist, but overall pattern still looks dry despite this. Temperatures near to above normal with weak ridging along the East Coast and a trough in the Midwest.<\/p>\n","protected":false},"excerpt":{"rendered":"
