One big weather story in the near-term that will likely become a big news story is the heat that will intensify across the Pacific Northwest later this weekend and early next week. As high pressure expands and intensifies over the Pacific Northwest later this weekend, many places including Seattle, Washington will approach or surpass the 100 degree mark for afternoon highs. In fact, Portland, Oregon could actually surpass their all-time high temperature record of 107°F on Sunday afternoon. In the longer-term, another weather story may develop across the tropics. A strong tropical wave has just exited off the west coast of Africa and signs point to a favorable pattern for intensification down the road potentially leading to problems for the Gulf of Mexico/Southeast US by the time we get to the early part of July.

An unsettled weather pattern will continue here right into early next week with a daily shot of showers and thunderstorms. Temperatures will generally peak out in the middle 80’s for afternoon highs and only drop to middle 70’s for overnight lows. Elsewhere, a heat wave will intensify later this weekend over the Pacific Northwest where temperatures could actually approach all-time highs in places like Portland, Oregon. Also, a strong tropical wave has just exited off of the west coast of Africa and it is something to keep an eye on and could have an impact on the US by early July.

An unsettled weather pattern will continue here through the remainder of the week with a daily shot at showers and thunderstorms and highs typically in the middle 80’s. On the tropical front, “Claudette” has departed the US mainland to a position over the western Atlantic and another system is headed towards the Caribbean Sea. This new system will need to be monitored over the next several days as it is likely to maintain some strength as it crosses over some warm waters in the Atlantic Basin.

A tropical system brought lots of rainfall to the southeastern states over the weekend and it has re-intensified back to tropical storm status (“Claudette”) and will exit off the Carolina coastline later today. Meanwhile, a strong frontal system will be dropping southeastward over the next couple of days from the Great Lakes to the east coast later tomorrow. It’ll stay rather moist across the Florida Peninsula and the daily threat of showers and storms will continue for much of the week.

A tropical system moving northward over the Gulf of Mexico should reach the Louisiana coastline later tonight – likely as a tropical storm which would result in the name of “Claudette”. There is plenty of wind shear over the Gulf of Mexico which is and will continue to limits its chances for any significant intensification. Once over land, this system will move to the northeast bringing some heavy rainfall to the Tennessee Valley and southeastern US later Saturday into Sunday

An active weather pattern will grip much of the eastern two-thirds of the nation over the next several days that will include a tropical storm, a severe weather threat from the Upper Midwest-to-Ohio Valley-to-Northeast US and then a blast of unseasonably cool air for much of the northeastern quadrant of the nation. The tropical wave is now pushing over the southern Gulf of Mexico and is likely to maintain a northerly track and reach the northern Gulf coastal region of Louisiana by later Friday night. After landfall, this tropical system will then move to the northeast and there is a chance that it actually strengthens some over land which is somewhat contrary to normal trends with tropical cyclones. In addition to the tropical activity, a severe weather threat will begin later Thursday across the Upper Midwest and will shift east tomorrow to the Ohio Valley and then perhaps into the Mid-Atlantic/Northeast US by later Friday night and Saturday. All of this active weather will be swept eastward on Tuesday with the passage of a powerful cold front that will usher in another much cooler-than-normal air mass for the northeastern quadrant of the nation.

A tropical wave will begin to turn the north today over the southern Gulf of Mexico and it is likely to intensify into tropical storm status by later Friday. On Saturday, this tropical storm is likely to be nearing the central Gulf coastal region and rainfall could spread into Mississippi and Alabama. After landfall, the tropical wave is likely to push to the northeast with its leftover rains moving into the Tennessee Valley on Sunday and Carolinas and Virginia by Monday. If this system does indeed reach tropical storm status (and that is quite probable), it would take on the name of “Claudette”.

There have been a couple of named tropical systems so far in the Atlantic Basin, but neither one was of much consequence and had little to no impact on the US mainland. A third tropical wave now drifting over Bay of Campeche and southern Mexico is likely to intensify into at least tropical storm status in coming days as it turns to the north, if so, it would become named “Claudette”. The track of this system is likely to bring it to the central Gulf coastal region during the early part of the upcoming weekend and then its remains are likely to push northeastward into the Tennessee Valley on Sunday and then the Carolinas/Virginia on Monday. There is even a chance that the remains of the tropical system strengthen after moving over land - contrary to normal trends for tropical systems - and it could get intertwined with an approaching cold frontal system to produce rainfall in the Mid-Atlantic region early next week.

The overall weather pattern will remain unsettled around here for the next few days given an abundance of moisture and upper-level troughing to our north. Temperatures will generally climb to the mid and upper 80’s for the remainder of the week and daily chances for showers and thunderstorms will remain rather high. Elsewhere, it looks like there will be a tropical system later this week over the Gulf of Mexico and we could be dealing with a tropical storm by the late weekend pushing northward towards Texas/Louisiana.
