KJ's First Warning Forecast
Steady rise between now and Friday... Triple-digit heat returns today before another cool down this weekend. Expect low 90s this afternoon, almost 10 degrees above normal for this time of year. Clouds will mix in and provide some relief along with a few showers and storms possible this afternoon. Otherwise count on a humid day with heat index values near or above 100.
Severe storm threat today and tomorrow... Inland areas are on the fringe for where there's an isolated risk for a storm to become strong to severe near Interstate 95 and on the Peninsulas.
Hottest day of the week is coming tomorrow. Highs Thursday will reach the mid 90s with a heat index to 105+. We will see a mix of sun and clouds with another chance for scattered showers and storms. The high heat and humidity may trigger heat alerts across the region.
Triple-digit heat once more to end the week on Friday, BUT the approaching cold front will bring much cooler and drier conditions for this weekend.

Tropical Update
Tropical Storm Nana likely to become a hurricane. Nana is centered about 145 miles east-northeast of Honduras and moving west at 17 mph. On the forecast track, Nana will be moving near but north of the coast of Honduras today and likely landfall on the coast of Belize tonight or early Thursday. Maximum sustained winds are near 60 mph with higher gusts. Tropical storm-force winds extend up to 70 miles from the center. Strengthening is expected, and Nana is forecast to become a hurricane later today or tonight before it reaches the coast of Belize.
Tropical Storm Omar moving away from the East Coast. Omar is centered about 315 miles north-northwest of Bermuda and moving east at 13 mph. A turn toward the east is forecast by this evening, with a reduction in forward speed occurring through Friday. Maximum sustained winds are near 40 mph with higher gusts. Little change in strength is expected through tonight. Omar is expected to weaken and become a remnant low by Thursday night.
Watching two areas for potential development in the Atlantic…
Disturbance 1: An area of low pressure has a low chance of further development as it sits between Africa and the Windward Islands. Right now, it's mainly showers and storms, but they are disorganized. It is still possible this system could develop as it hangs out over the tropical Atlantic.
* Formation chance through 48 hours: Low (20%)
* Formation chance through 5 days: Low (30%)
Disturbance 2: A tropical wave emerging off the coast of Africa. A slow progression towards development is expected over the next couple of days as it merges with an area of disturbed weather nearby. A tropical depression could form by the weekend as it moves west towards the central Atlantic.
* Formation chance through 48 hours: Low (10%)
* Formation chance through 5 days: Low (60%)
