 Happy Father’s Day!  This morning will end up being the best part of the day as clouds increase and sunshine fades.   A frontal system is going to pass through the area late today and with it comes the chance for showers.  Dry conditions overall will continue through the morning with the chance of showers increasing after 4 PM.   Temperatures will peak early this afternoon before falling back as the clouds thicken.

I'll be updating the details of the showers on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.

Any showers we see will end overnight.  This morning was quite chilly with Berlin, NH falling to 37F.  Many other communities recorded readings in the 40s. Tomorrow morning won’t be as chilly.  By morning temperatures will be in the 50s under partly cloudy skies.  Monday dawns partly to mostly and continues that way all day.  There is a renewed chance of showers in the afternoon and evening, but like today, many of us will stay dry.

You will notice a bit of humidity in the air Monday as dew points, a measure of moisture in the air, creep upward.  This isn’t going to be a long lasting or particularly intense bout of sticky conditions, just a change from the dry air of the past couple of days.  I am forecasting highest temperatures between 74F and 78F around 3PM.
As a new weather system tries to cross through the area Tuesday showers continue in the forecast.  Tuesday has the best chance of showers this week, but even that day isn’t a washout and there will be sunshine.   Model data is a bit conflicted for how fast weather moves along on Tuesday.  The Euro is going with a slower moving system and keeping clouds and the chance for showers going much of the day.  I tend to favor the European’s slower solution to Tuesday’s weather.  Humidity will be high in the morning before falling back to drier levels in the evening and overnight.  Highs on Tuesday reach the upper 70s in spite of the lack of full sunshine.
The rest of the week is looking mighty fine.  There will be sunshine and highs reaching the 70s.  Nights will be comfortably cool for sleeping.   The reason for this patterns is the jet stream  is remaining positioned in such a way as to keep any heat and humidity away from New England.  During the summer air that comes from the northwest provides us with some of the most comfortable conditions.   Because there are no large bodies of water in Canada air in that region doesn’t contain much moisture.  We call this continental polar air (cP).  You can contrast cP air with maritime tropical air (mT).  That is the sticky warm stuff many of us don’t like.  There are two other basic types of air masses affecting the lower 48 and these are continental tropical (cT) or dry warm air and maritime polar (mP) cool moist air.   Most of our weather is caused by these air masses each fighting for domination and bumping into one another.
Astronomical summer begins later this week which means the longest day of the year is upon us.  I put a chart for sunrise and sunset below.  As you can see we will still gain a tiny bit of time this week, but this weekend we lose a few seconds of time, don’t worry you won’t notice it just yet.

Gardening this week With all the rain this month your soil might be water logged. Raised beds are a great way to grow flowers, vegetables, even trees and shrubs when you have limited space or need to create a new growing area. In the following video watch how we create a raised bed for a suburban homeowner. You could do the same thing anywhere by just changing the scale to fit your needs.
