Ah holiday weekend forecasts. Always high stakes. This one, as a whole, isn’t too difficult. We will not be basking in beautiful, summery weather. That’s a near certainty. Daytime temperatures are going to be cooler than normal throughout the entire 3-day stretch and sunshine will be limited. And it will not be rain-free. But there [...]
A storm center moving out of the Central United States today will press toward the Eastern Seaboard over the course of the next couple of days, bringing a period of unsettled weather for the second half of the week. A series of low pressure centers will move through the Great Lakes today and Thursday and [...]
A warm front crossed through the region last night, bringing some well-timed and welcomed rain to the Cape and Islands. Some rainfall totals around the area include: Brewster .53 inches Barnstable .36 inches Hyannis .38 inches Chatham .40 inches Martha’s Vineyard .21 inches Nantucket .33 inches The warm front is now passing to our north [...]
New England is sitting pretty today, located nicely between two weather systems. Moisture off to our northeast and southwest is trying to converge on the region but will be held at bay for the time being, leaving us with a sunny and mild Saturday. Temperatures will get into the 60s today and winds will be [...]
A nice, warm spring airmass is pushing through Southern New England today. Temperatures in the 50s early this morning jumped quickly into the 60s not long after sunrise and by mid-morning have already been flirting with 70F. This, despite the presence of some mid-level cloudiness associated with a frontal zone south of the region. As [...]
A warm front pushing across the Northeast today will produce a band of clouds and some showers as it crosses New England. Here on the Cape, clouds will thicken during midday and we’ll look to the west for a few approaching showers later this afternoon. A couple of brief downpours will be embedded in the [...]
As recreational boaters gear up for a summer of fun on coastal waters and the Great Lakes, NOAA is testing MyNOAACharts, a new mobile application that allows users to download NOAA nautical charts and editions of the U.S. Coast Pilot. The app, which is only designed for Android tablets for the testing period, will be [...]
The April average temperature for the contiguous U.S. was 49.7°F, which was 1.4°F below the 20th century average. April 2013 ranked as the 23rd coolest such month on record and marked the coolest April since 1997 when the monthly average temperature for the contiguous U.S. was 48.0°F. Climate Highlights — year-to-date (January — April) The [...]
On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks [...]
The National Weather Service completed the dual-polarization technology update in Brownsville, Texas – concluding the 122 NWS radar site upgrades throughout the country. This new advanced technology is helping federal weather forecasters more accurately track, assess and warn the public of approaching high-impact weather. Dual-polarization is the most significant enhancement made to the nation’s federal [...]
Soil moisture content for April was (not surprisingly) below average here in New England – with more of the damage being done during the second half of the month thanks to the combination of green-up and little in the way of rainfall going back . Will things improve in the coming days? Overall, the pattern [...]
Much like last year, April 2013 was rather dry across most of New England. The exception to the rule was actually here on Cape Cod where precipitation averaged out closer to normal (though still somewhat below the long-term average) While Boston picked up a measly 1.37″ of precipitation (2.37″ below normal), Hyannis recorded a much [...]
After a cool shot of air this weekend (one that could actually bring accumulating snow to the high terrain of VT and NY!) may we be looking at a really nice taste of summer weather later next week. While this week was rather muggy and did feature one exceptionally warm day over the interior…much of [...]
A soupy airmass combined with a favorable jet stream configuration is really working to pump out heavy rains today across the Mid-Atlantic and parts of the Northeast. Our turn comes tonight into tomorrow. Here’s a look at the high resolution (4km version) NAM model precipitation ending 8PM Friday evening (the 18z run). This is likely [...]
Looking at the possibility for some heavy rain Thursday night into Friday (before the coastal low takes shape and gives more rain for the weekend). Ingredients in play: 1) simplest – driving a potent cold front into a moist air mass 2) strong (unusually strong for late May – note on image below multiple SD [...]
High pressure way up in central Canada today will gradually shift south and eastward over the course of the next few days, giving the Cape a nice lesson in the importance of wind direction – especially in the Spring. Today, winds across most of New England blew strongly from the west – or offshore – [...]
A shortwave and associated surface low pressure passing west to east, north of the Great Lakes, will drag a warm front across the Northeast and New England on Wednesday and Wednesday night. Guidance is showing a batch of precipitation associated with the frontal boundary and there is a bit of an instability burst associated with [...]
Things will become more seasonal next week behind what should be the last big intrusion of “arctic” air this weekend / early next week. Notice how much more relaxed the upper air pattern becomes when we compare this weekend to late next week on the euro ensembles. Most of the Northern Hemispheric teleconnectors are headed [...]
The sun is about to come up over the South Pacific Ocean in this colorful scene photographed by one of the Expedition 35 crew members aboard the Earth-orbiting International Space Station between 4 and 5 a.m. local time, May 5, 2013. The space station was at a point above Earth located at 27.4 degrees south [...]
WASHINGTON — NASA’s Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the “habitable zone,” the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. The Kepler-62 system has five planets; 62b, 62c, 62d, 62e and 62f. The Kepler-69 [...]
A new study using data from NASA’s Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class of objects that are used to measure the rate of expansion of the universe. Astronomers have used a very long Chandra observation of the [...]
A team of astronomers using NASA’s Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that’s been around for a very long time. “We have found that this is the oldest known star with a well-determined age,” said Howard Bond of Pennsylvania State University in University Park, [...]
PASADENA, Calif. – A distant world gleaming in sunlight, Earth’s twin planet, Venus, shines like a bright beacon in images taken by NASA’s Cassini spacecraft in orbit around Saturn. One special image of Venus and Saturn was taken last November when Cassini was placed in the shadow of Saturn. This allowed Cassini to look in [...]
Daylight Saving Time Begins! Sunset will keep pushing forward to 5:41pm by the time we adjust our clocks an hour ahead on March 10th. By the end of the month, sunset will be at 7:05pm. Those of us who don’t enjoy the short days of winter can start to let out a sigh of relief. [...]
WED AM – Low clouds and fog moved in overnight and really thickened up over Southern New England. As a result, we’re starting our Wednesday quite gray and a bit cool. Gradual improvement this afternoon with temperatures mainly in the 60s.
THU PM – Clear skies and temperatures still in the 60s as of 9PM. not a bad night on Cape Cod.
THU MIDDAY – P. Sunny and mild this morning. Becoming sunny by early afternoon. Temps jumping into the 70s.
