    The Memorial Day Weekend forecast has a number of tricky aspects to it beginning Friday evening and continuing right through Monday.

    Temperatures on Wednesday topped out in the lower and middle 70s across most of the Cape, although some south-facing spots right along Nantucket Sound held in the upper 60s thanks to a wind off the water. After a murky early morning, the day featured plenty of sunshine and a busy, […]

    Last night’s low clouds and fog began to lift and thin not long after sunrise and we’ll see sunshine take hold of the area over the course of the morning hours, with clear skies expected from late morning through the afternoon hours. It will turn much warmer as temperatures jump […]

Consequently, there is […]

Bit Dreary Today

An upper level low pressure center lifting northward across the region has spread a shield of clouds, showers and areas of mist and drizzle into the region today. While the Cape hasn’t picked up much rainfall, it’s been a rather damp, dreary and cool start to our Tuesday as a […]

Wednesday’s Temperatures Warmest Since Last September?

Temperatures so far this month have averaged out 1 to 2F below average around the region. At Hyannis the temperature has only cracked 70F three times thus far this month (70, 71 and 70F). As a comparison, through May 22nd, 2015, Hyannis had reached 70F or greater 7 times during […]

Green-Up From Space

Our recent run of wet weather followed by this week’s sunshine and warmer temperatures have really pushed the spring “green-up” along nicely. Take a look at the changes – as seen from space – over the last 2 weeks.

Changing the Wind Direction Made a World of Difference

After holding in the 40s and 50s for nearly a week straight…temperatures finally busted out into the 60s today. Obviously the addition of sunshine played a major role in that big temperature jump, but the wind was equally important. A cold northeast wind dominated the weather all of last week, […]

Temperature Trace Last 7 Days

Hard to Believe But…

…the average high temperature for May 6th at Hyannis is 61F. Yesterday readings were stuck in the 40s (again). In fact the high only managed to reach 46F at Hyannis and 45F at Chatham – which is just a few degrees above the average low temperature for this time of […]

Beneficial Rains

While we’ve had to endure plenty of ugly weather in recent days, we have at least picked up some very beneficial rain. Although April precipitation wasn’t far from normal (just a bit below average) most of the month’s rain fell during its first 7 days. The final 3 weeks of […]

Pretty Bleak Stretch

It’s been an awfully nasty stretch of weather given the time of year. Clouds moved in and onshore winds took hold several days ago and have left us longing for even just a few glimpses of sunshine and near normal temperatures. We’ve had a good dose of rain but the […]

Nice Day Around The Area

Mid and high level clouds have dimmed and blocked the sun now and then but overall cloud cover has remained rather limited and allowed for a decent amount of blue sky and sunshine today. Temperatures have been well into the 60s and winds, while still busy, have been much more […]

Rain Continues to Back In Off The Ocean

We’ve had upwards of 2 inches of rain across parts of the Cape so far this week and we are simply adding to the totals today. Radar continues to show rain pivoting in off the ocean as low pressure organizes to our east and gradually lifts northward. Expect this rain […]

Nasty May Evening

Temperatures in the lower and middle 40s, heavy rain, some thunder and northeast winds gusting to 20 to 30 mph at times. This is about as nasty a May evening as we can manage on the Cape. One-half to one-inch of rain has fallen across the area with some additional […]

Rain Pushing Offshore

A steady chilly light to moderate rain throughout the first half of Tuesday is gradually coming to an end. Precipitation is tapering off and heading seaward as of mid-afternoon. Rainfall amounts have generally been in the 1/4 to 1/2 inch range…with the lowest amounts on the far Outer Cape. Unfortunately, […]

Rain, Wind, Likely Saturday Night Into Sunday

We have two more days of nice weather to go before things go downhill. Friday and most of Saturday should be quite nice around the region with sunshine and mild temperatures – highs nearing 70F Friday afternoon, in fact, and probably getting pretty close to that mark on Saturday as […]

Keeping An Eye on Saturday’s Weather

While high pressure is locked over the region and providing us with a long period of storm-free weather, there’s always something to keep an eye on from a forecasting standpoint. In this case, the main forecast questions revolve around Saturday’s weather. An offshore storm will wobble westward a bit toward […]

Strongest Wind Between 8AM-Noon

Wrong Direction

There is very strong model agreement for a stretch of unseasonably cold – if not record cold – air to invade the northern tier of the country in a little over a week’s time. In response to a building ridge over the Eastern Pacific and into Alaska next week, a […]
