Ask Eric: Why Does Humid Air Melt Snow Faster?
Squeeze Play!Enough dry air will remain in place Wednesday that there will be breaks of sun inland early, but clouds will be quickly filling in as the squeeze will be on between the departing ocean low and an approaching cold front. Cloudy skies with light NE winds will spell highs in Lwr-mid 60's. This front could trigger a few late showers in the far NW portions of New England late Wednesday. Most of the shower activity with this front will come Wednesday Night through early Thursday morning.
A 'Top 3' Week To Start Autumn
Humidity About To Break...Behind the warm front, warmer, steamy air with hazy breaks of sun as a dry slot shifts north for the afternoon. Highs climbing into the upper 70's and Lwr 80's south. We will have to watch for scattered showers and storms to start popping again across SNE during the afternoon and possibly form a line of stronger storms which could form and maybe even some severe weather if we get enough sun to break.
Storms To Break The Heat WaveThe Severe Storms Prediction Center issued a Severe Thunderstorm Watch until 8 PM tonight for Northern Western and Central New England.
Back on Track...But Still Cool
Rain Will Change To Snow For All By Sunday Evening If you are aching to get out and shovel, you can get started now, but there may be another inch or two by the time it all ends later.
Weekend Storm Appearing More LikelyMost roads and pavements will remain wet so traveling will not be an issue today. These morning bands of snow are part of an Arctic front which is breaking down the unseasonal warmth from Friday. Once this front pushes off the coast, we will wait for round #2 to come up the coast. How far this front pushes off shore could help to determine the how close this next storm will track to New England.
Plenty Of Summer Left In The Tank!Our computer models continue in a westward shift with the track of Tropical Storm this morning. Yesterday, models leaned towards taking the storm into the FL panhandle. Today, they seem to be favoring a track into Louisiana. There is still a great deal of uncertainty with the eventual outcome of landfall...somewhere between Pensacola FL and New Orleans Early Wed AM. How strong? Cat 2 likely. 100+ mph...but could be stronger depending upon the track and the depth of the warm water the storm tracks over. Cat 3 can not be ruled out. Storm Surge will be dependent upon the strength of the storm as seas/waves become bigger with deeper pressure falls and stronger winds. Where ever this storm hits it will come with significant storm surge flooding and damaging winds. All of this happening on the anniversary of Hurricane Katrina. The path into New Orleans is the worst direction a hurricane can take for the city 6 feet under sea level. Levees could be tested again. All we can do is hope for a shift to the East...but then Mobile, Biloxi and Pensacola are the target. Answers to strength, track, surge, impact will come in the coming days. For now...all we can do is monitor.
An Eye on Isaac and The WeekendA more humid feel to the air this weekend with dewpoints climbing back into the mid 60's after such a nice comfortable week. This weekend will be dominated by a high sitting over the Canadian maritimes wrapping in a light onshore wind.
July Heat Wave & The Northern LightsSkies will become partly sunny this afternoon with light to breezy west winds, highs will climb into the upper 80's and Lwr 90's in most areas. Clouds this morning at the beaches will give way to an afternoon haze. Where clouds linger longer, this will help to keep temps mostly in the 80's.
Stalling Front Will Mean Increased Humidity and Chances of T'StormsGorgeous day in progress with sunshine, lower humidity and a gentle onshore wind. Highs will be climbing into the upper 70's and Lwr 80's inland. Beaches will be cooler with temps in the upper 60's and lwr 70's
