On Tuesday we rose to around 80°. A cold front swept through early Wednesday, switched our winds to the north, and we are seeing highs in the 60s. The warmer air has been pushed to the south. This cool air will be around a few days then we are in for a weekend warm up.
This front was sent south by a storm system in the Great Lakes that is now shifting south into the Midwest. We will not see rain from this system, but some periods of clouds will be possible as they get sent back west. We are basically in between the closed low to the east and the main jet stream well to the northwest. The low is cut off from the main jet stream and will wander a bit through Saturday. If it drifts far enough west, then we could see much more cloud cover Friday and Saturday. As is, we will go for a sunnier forecast and a warm up to the 70s. If there are more clouds it may take until Sunday to reach the 70s.
SUNDAY-MONDAY: Look at the change from the upper level flow Wednesday (above) and the upper level flow for Sunday. The jet stream to the west is diving south into the Rockies. This will likely produce our next chance of thunderstorms by mid next week as the pattern undergoes a big change. The upper level low to the east weakens and drifts back north. We are still in between the two systems and will see a warm up to highs close to 80°. As we go beyond this period there will be many changes in the pattern. At this time, there is much uncertainty as to what is headed our way.
There is something more certain. We know the Chiefs play in Pittsburgh on Sunday night, right here in 41 Action News for Sunday Night Football in America. It looks like the upper low will lift north just in time, so that Sunday evening will be dry and mild in Pittsburgh.
TROPICAL TROUBLE: Tropical Storm Matthew has formed east of the Caribbean Sea. He will likely intensify and move west into the Caribbean then head north and either affect the Gulf coast or east coast next week. We will be hearing quite a bit more about this in the coming days.
