You might have noticed a slight change in the air mass over night as slightly less humid air worked into Maine.

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

 Temperatures fell into the 60s across most of the area and it has been a nice morning.  Inland areas will approach 90F once again, but if your town does hit that mark, it won’t last very long.  There will be a blend of clouds and sunshine today, not a bad day to head to the beach.

 

A few things are going to change this week and some will stay the same. First, humidity levels will remain noticeably high nearly the entire week.  We might get a break towards the weekend, but that is still not a sure thing.
 
No areas will see a heat wave this week.  Showers and thunderstorms are possible nearly the entire week, but the most likely days you will get wet are tomorrow, Wednesday and Thursday.   The showers tomorrow, if they manifest,  will do so earlier in the day. Some of the rain could be quite heavy in the occasional thunderstorm.  
 
If you are on vacation this week, it won’t be a washout, but it’s not going to be perfect beach weather.  In these patterns it’s important to realize the showers won’t occur all day and there will be many hours of dry weather.
 
This pattern of high humidity and warm temperatures isn’t that unusual.  July is the core of summer in the same way January is the core of winter.  It is very difficult to get many days of cool Canadian air this far south in July.
 
As the days continue to get shorter the jet stream will have an easier time pushing drier air into the region more regularly.  This usually won’t happen until mid-August.  It’s not likely it will take that long until we see a break in the humidity, but we tend to have more sticky days than drier ones until that time.
 
This summer has been significantly cooler for the middle of the country.  Checks out the two maps below showing how far off normal temperatures have been the past two years.  These maps are for the past 90 days.  Notice New England is about as warm this year as last, but the middle of the country is significantly cooler.  (they have been wetter as well).  This is important to New England because when the center of the country is hot and dry it affects farmers and in turn food and fuel prices.

Gardening this week Are you growing tomatoes this year? If you haven't gotten a tomato plant yet there is actually still time, you might not have tomatoes until late August or early September, but you can still plant. This week, I have a video about my rescue of a tomato plant and how to grow them in containers.
