 This has been quite an October for warmth.  So far in Portland just a few days have been in the 50s and 15 day have reached or exceeded 60F.  We even had one 80 degree day this month.  Temperatures are running shy of 5 degrees above what you would expect and there has yet to be a frost along the coast.

I'd love to hear your thoughts on weather, climate or gardening or even education with you. Please find me on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.

Today and tomorrow will be the last of the mild days for a while, any more days in the 60s will be rare and don't expect them to come in clusters either.   Sunshine is abundant this afternoon, but fades tomorrow as a cold front pushes through the region.  
I suggest finding some time to get outside today, as it is my pick of the week.  Even if you just take your lunch and sit on a bench for a few moments, see if you can carve out the time.  Later this week, it will  feel dramatically different.
Check out the two maps below, the first shows highs this afternoon, the second highs on Wednesday.  Some areas will see a 20 degree change in maximum temperature in this 48 hour period. Many inland areas in southern Maine could stay in the mid 40s all day Wednesday.
World Series Weather
As the front ushering in the cold air crosses the area late Tuesday night a storm will develop along the coast Wednesday and move up to our east.  This is a nor'easter and the exact track of the storm will determine just how close to the coast the rain shield gets. 
 If the storm came 100 miles closer than forecasted, there is little doubt game 1 of the World Series would be postponed.   Even on the current track, some light showers are likely and temperatures are going to be cold.   For those folks sitting in Fenway Park who have never been to an April game, they will know what it feels like Wednesday evening.
The maps below show the position of the storm and the predicted radar Wednesday.  There are showers in the Boston area.
Late Week:Frost/Freeze
The second part of the week is going to be cold.  After the stretch of weather we have just enjoyed, the shock will be quite apparent.  Temperature are normally in the lower  50s by the end of the month, so the cold air is quite typical, it's just that we haven't had any.   As I mentioned, the coast has still not had their first frost. This will all change Friday and Saturday morning when many spots away from the water will experience temperatures in the upper 20s.  If you have not brought your plants into the house yet, you have a couple more days to get it done.
Lack of rain
Assuming we don't get much rain Wednesday, we still don't see any significant rain in the forecast.  The next chance of showers comes late Saturday night or Sunday, but doesn't look like much.  The deeper into the fall we go without significant precipitation, the more important significant snow is going to be this winter or we are headed for a drought.
