Very Nice Day Today
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 [...]
Mild Thursday
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 [...]
Breezy, Milder Today. Showers Possible.
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 [...]
Milder Air Returns
The chilly polar airmass that moved in to start the work week will shift seaward tonight and tomorrow. Temperatures will moderate throughout the day on Wednesday, getting back to seasonable mid-May levels (lower to middle 60s) by early afternoon. A warm front will cross the region Wednesday night, bringing afternoon cloudiness and some isolated to [...]
Cool Pocket
A dip in the jet stream over the northeastern corner of the Lower 48 states is bringing a shot of unseasonably chilly air into the Great Lakes and New England today and Tuesday. Frost and Freeze Advisories have been posted by the National Weather Service from the Mid-Atlantic northward to Southern New England and parts [...]
Nice Finish To Our Mother’s Day
Some much needed rain pushed through the area later Saturday and through Saturday night. Showers lingered for a time this morning but are in the process of shifting offshore as of late morning. The latest visible satellite image (as of 11AM) shows the clearing line making nice progress across Southern New England. Brighter skies will [...]

Coolest April in U.S. Since 1997
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 [...]
Carbon Dioxide at NOAA’s Mauna Loa Observatory reaches new milestone: Tops 400 ppm
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 [...]
NOAA’s National Weather Service completes Doppler radar upgrades
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 [...]
A Look At Soil Moisture
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 [...]
Dry April For Much of New England
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 [...]
March was cool and dry for the contiguous United States
Climate Highlights — March The March average temperature for the contiguous U.S. was 40.8°F, which was 0.9°F below the 20th century average. This was in stark contrast to temperatures from one year prior when March 2012 was the warmest such month on record for the nation. 2013 marked the coolest March since 2002, when the [...]

As Always – Wind Is Everything On Cape Cod
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 – [...]
Showers, Some Thunder, Possible Wednesday Evening
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 [...]
Pattern Settling Down
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 [...]
Looking Better
Half of this image represents model la-la land but it shows some positive signs and is supported by other guidance – in general. After a prolonged period of very dry (albeit quite nice!) weather, the weather pattern is showing signs of finally breaking down across the Lower 48 states. Consequently, weather systems that have been [...]
So You’re Telling Me There’s A Chance.
Energy over the central U.S. – associated with the same trough that’s brought a historic May snowstorm to the Northern Plains and Upper Midwest – will gradually close off into a very slow-moving upper level low pressure center over the course of the next couple of days. This upper air storm will sink southward through [...]
Omega Block
Guidance is signaling a quiet weather pattern for the coming days as a large high pressure area sets up over New England later this week. Looking into next week, the ecmwf shows a stable “omega block” taking shape from the central US to the western and central Atlantic ocean, with the core of higher heights [...]

Sunrise Over the South Pacific Ocean
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 [...]
NASA’S Kepler Discovers its Smallest ‘Habitable Zone’ Planets to Date
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 [...]
Famous Supernova Reveals Clues About Crucial Cosmic Distance Markers
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 [...]
Hubble Finds Birth Certificate of Oldest Known Star
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, [...]
Cassini Spies Bright Venus From Saturn Orbit
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 [...]
