US: All Eyes On Gulf Next Week, East Coast Rainstorm Also A Possibility

Written by on September 25, 2015 in Autumn 2015, United States of America with 0 Comments

We’ve two areas of concern through the next 5+ days, the first is the system gathering force off the Carolinas bringing flooding rain, gusty winds and beach erosion to the Mid-Atlantic. This will move into the Northeast through the weekend on into early next week.

Big rains yesterday for the Carolinas.

The other area of concern is a disturbance gather near the Yucatan. As previously stated, at this time of year when heights soar into Canada, heights tend to fall away into the subtropics and tropics and we’re seeing that. Warm water, favourable upper winds etc mean the Gulf Coast is open to attack next week.

Overall, this is a very wet pattern for Southeast and East.

ECMWF shows rain and wind battering the Mid-Atlantic while disturbed weather brings similar conditions to the Upper Texas coast early Sunday.

As we enter early next week, the East Coast system looks to but note what’s coming up out of the Gulf while a cold front drops out of Canada.

Towards mid week, the ECM takes the Gulf system onshore, exactly as what remains to be seen while the cold front dropping out of Canada significantly weakens as the large scale height field is too much.

Interestingly the model appears to see more ‘development’ of the Gulf system as it meets the southbound CF which redirects it up the Carolina coast. This could be a big rainstorm up the East Coast late next week.

Course you only need look at the above QPF and East Coast rain totals next 10 days to see a lot of rain is coming.

The ridge looks to remain dominant across much of the US through the first half of October but this setup always leaves the Gulf and Atlantic exposed to anything out in the tropics.

This makes for a largely warmer than normal pattern.
