A Little Break
Posted by Brent Cameron
We're catching a break with quiet weather conditions, now. Will it last throughout the rest of the week? no! Our weather maps clearly show a disturbance to our southeast which should impact our local weather by Thursday night or Friday. It's a tropical wave with plenty of associated moisture.
Upper atmosphere charts show a quick transition from "dry" to a very moist environment. As the moisture levels increase, we'll be in a position to receive rounds of rain with thunderstorms. Usually, when such thick moisture is over us (especially this time of the year) we get heavy downpours with the concern for localized street flooding. Stay tuned.
For the time being, drier-than-normal air is in place. Further, we're even getting a beneficial breeze off of the Atlantic Ocean. With mostly dry air around (and limited instability) rain chances will remain very low through the middle of the week. However, by Friday, our dry air wedge will be pushed out... so a steady supply of tropical moisture will enter the region.
In the tropics, we're following the "last bit of life" from Ernesto. It made its initial landfall near Chetumal (already) and has emerged over the Bay of Campeche. Over the next 24 hours, it will make a second landfall... along the central Mexico coastline, this time. Also on the tropical weather map is a vigorous tropical wave that's impacting the Caribbean islands. If the wave can hold together, the northern extent of it COULD impact the Bahamas and south Florida by Friday. Meanwhile, we'll be keeping watch on a possible disturbance forming in the central Atlantic. For now, the Hurricane Center is giving it a "medium" development chance.
