On Tuesday, look for mostly to partly cloudy skies, breezy conditions and warm temperatures with an 80% chance of showers and thunderstorms. Morning lows will be in the upper-70's and afternoon highs will be in the mid-80's. Expect southeast winds at 15-20 mph, gusting to 25-mph.
A tropical wave should reach the coast late today or early tomorrow, accompanied by a surge of deep Gulf moisture. We should see a dramatic increase in clouds and rain chances over the coming 24-36 hours. So, partly cloudy skies and hot conditions will prevail early today, but will give way to an increasing chance of showers or thunderstorms later today into tomorrow. Brisk southeast winds will accompany the moisture surge as it moves into our area..
This morning, a slow-moving cold front extends northeast and east from near Death Valley to lows over northeast Nevada, northeast Colorado and northern Minnesota. High pressure is found behind this front over Canada and the Pacific west of Vancouver. Elsewhere, isolated lows are seen near San Francisco and over the northern Gulf of California. IN the East, a cold front is sagging south into New England, while high pressure is located in the Atlantic east of North Carolina.
At the Upper-Levels, a mid and upper-level high pressure ridge extends northward from Cuba and Florida across the Deep South to the Midwest as well as ridging west into Louisiana, Arkansas and East Texas. Meanwhile an upper-low persists over the southern and southwestern Gulf of Mexico. In the West, an upper-level low is found over Oregon with an associated low pressure trough digging south to Arizona, Southern California and northwest Mexico.
Generally dry and warm conditions early today will give way to increasing clouds and rain chances as a tropical wave, interacting with an upper-level low, moves towards the Texas coast accompanied by a surge of deep Gulf moisture. There will be a good chance of significant rain later today into Wednesday. This is some indication that the upper-level low will shift west towards the Mexican coast by the middle of next week, keeping rain chances in our picture a while longer. While tropical development in the Gulf is still possible, chances remain low (20%). Nevertheless, heavy rain. brisk winds and somewhat elevated tide levels will be likely over the coming five days or so.
TROPICAL OUTLOOK:A tropical wave over the Yucatan is given a 20% chance of developing over the coming five days.
