Dry and Cool Weather Coming Up

It's been a great end to the work week!  A huge relief, especially after all the rain that we've had.  We have a high pressure system up to our north, which has helped keep the skies clear and keep the temperatures more mild.  The nice weather stays with us through the overnight, where temperatures will cool down to the upper 50°s.  Temperatures will cool off more quickly after sunset and because of that, we may see some light fog during the overnight.

The high pressure influence will keep the beautiful weather in our area over the weekend, with temperatures staying in the low 80°s and the humidity staying low.  The reason for the quick change from hot and humid weather to cool, drier weather is actually having to do with something out east.  The large high pressure system over the Great Lakes will be pulling cooler air down into the tropics, which will create a strong low pressure system off the east coast.  The low will strengthen the inflow of cooler air, resulting in the upper level jet developing a trough over the deep south.  To the west of the trough will be an area of sinking motion, which will help to further strengthen the high over the Great Lakes and keep the dry weather with us through most of next week.

A low pressure system will move up north of us in Canada on Wednesday, but it'll have an extended cold front move towards our area, bringing us the chance for some rain in the afternoon.  We're only expecting less than an inch of rain.  This won't raise river levels, but it may stall the river levels for a couple of days.  However, by Wednesday the river levels will be closer to minor flood stage levels, so even though they'll stall they're not gonna be a dangerous levels.

Other than Wednesday, the high pressure system will dominate all next week, keeping the skies clear and temperatures on the cooler side.  We'll start the work week in the low 80°s, cooling down to the mid 70°s by Thursday.
