Here Comes the Heat ...

Discussion:

If you like heat and humidity … you will love Sunday – Wednesday of next week.

Remember our 3-day stretch of heat in May?  Yea, distant memory I know, but this coming 3-4 day period starting Sunday looks similar. And it will not last, as it will cool, and moisten up by the end of the week and next weekend.

What we have is a trough over the eastern US that has resided here for some time. It has kept us comfortable to cool (depending on your liking) and generally moist/wet. Now a major trough is entering the west coast, and a major ridge will surge in to the east, kicking the old trough out of here.  This ridge will likely produce our first widespread heatwave of the summer season. Mon – Wed will likely reach 90 degrees or higher. However, the tricky forecast is Wed.

An area of high pressure in central Canada will be sliding to the SE, but staying to our north. This should push a boundary south of us and turn our winds to the E-NE. This happened in May and could happen again. If that boundary is early, Wed is much cooler, as is Thu … but if later then Wed is very hot but Thu is still cooler. Right now, I am going in-between the two. A hot start to Wed, but cooler overnight with a cooler Thu as well.

The humidity will also increase later next week as a trough looks to redevelop in the central US. This places a ridge over the west and one just off the east coast. This puts us in a mild/warm but humid and moist flow: thunderstorms with heavy downpours. But that is a week away.

The Dailies:

• Thursday: Mostly sunny. Seasonally cool.
• Friday: Mostly sunny. Warmer. Chance for a shower and thunderstorm late and overnight as weak system moves through.   
• Saturday: Partly to mostly sunny. Slight chance for a shower/thunderstorm.       
• Sunday: Sunny. Much warmer.
• Monday: Sunny. Hot.  
• Tuesday: Sunny. Hot. Humid.  
• Wednesday: Mostly sunny. Hot. Humid. Chance for a shower or a thunderstorm.
