Last week we had nice spring-like temperatures (60 degree highs) and clear skies. This week it has disappeared, with cloudy / rainy conditions and highs in the 40′s and 50′s. However springtime it’s coming back this weekend, but possibly with a bang. Look at the NAM MOS for this weekend in Laconia, NH:

That’s right, 82 degrees for a high temperature this saturday. So it looks like summer is coming a little early
For my Transportation Project: Aviation Sector, I did a case study about the plane crash on the evening of February 12th, 2009. Before I go on, I would like to say that this is not published work, and the investigation by the NTSB is not finished.
Here are some of the weather conditions that evening that may have contributed to the crash:
- Cold front with cloud cover and snow
- High RH column from 55o hPa to Surface
- Temperatures at or near freezing at the surface
- Moderate Visual Flight Rules (ceilings < 3000 ft and visibility < 5 miles)
These are all good conditions that clear ice, the most dangerous form of ice for an aircraft, will form. While an NTSB’s report on March 25th 2009 (source) said that icing was occurring that evening, it was not the main factor.
Nonetheless this is a tragic story and weather can be very nasty at some times.
The day after the Superbowl is one of the most depressing days in the sporting year. Football fans (like myself) are stuck with only hockey and basketball for a few weeks. But as spring nears our spirits are lifted by two things: March Madness, and Red Sox opening day
Tomorrow the Red Sox begin their 2009 Season as they play at Fenway Park against an opponent now worthy of being called a “competitive” team: The Tampa Bay Devil Rays. This rematch of the ALCS will be exciting, as Josh Beckett takes the mound at approximately 2pm tomorrow to start a 3 game series.
Unfortunately that 2pm starting time may not be exact, as a low pressure system will creep up the east coast and bring rain into the area. It should start around noontime, and persist and get heavier throughout the day. We may see a rain delay turn into a rain out. Tuesday looks more promising, and with no game scheduled that day, we may see the game rained out til Tuesday.
And remember, if it does get rained out, I am not liable for anything, so dont yell at me 
SOURCE: Plymouth State Vortex
Springtime hit Plymouth today like a sack of bricks. The high temperature on the roof of boyd hit 63.9 degrees fahrenheit. This meant that all the kids were out playing on the fields (and out of the library…which is where I am currently located)
See we graduate students cannot enjoy these days. I don’t mind it. I’d rather go over the synoptic conditions as to why it’s such a nice day.
Unfortunately it isn’t going to last. Low pressure system (which is wreaking havoc on the southeast today) will move into our area tomorrow, giving us a chance of showers and cooler temperatures
