Meteorologist Myles Henderson’s First Warning Forecast

Another taste of summer… Highs will climb to the low 90s today, about 10 degrees above normal for this time of year. It will feel more like the mid 90s with building humidity. Expect mostly sunny skies today with a few clouds mixing in this afternoon.

Expect partly cloudy skies on Wednesday with an isolated shower possible. Highs will reach the upper 80s, but it will still feel like the low to mid 90s with the humidity.

Scattered showers and storms are possible for the end of the week as a cold front moves in and an area of low pressure builds along the coast. Highs will drop to the mid 80s but it will still be muggy, making it feel more like the upper 80s to low 90s.

Today: Mostly Sunny. Highs in the low 90s. Winds: S 5-10

Tonight: A Few Clouds. Lows near 70. Winds: S 5-10

Tomorrow: Partly Cloudy. Highs in the upper 80s. Winds: S 5-15

Tropical Update
Tropical Storm Nicholas moving slowly toward Houston. Nicholas is centered about 15 miles SSW of Houston, Texas and moving NNE at 8 mph. The storm should move more slowly to the northeast later today, and then turn east by Wednesday over Louisiana. Little motion is anticipated on Thursday. Data from NOAA Doppler radars indicate that maximum sustained winds have decreased to near 60 mph with higher gusts. Nicholas should weaken further today as it moves farther inland, and the storm is forecast to become a tropical depression by Wednesday morning.

A tropical wave accompanied by a well-defined low pressure system is located about 400 miles southeast of the southern Cabo Verde Islands. Environmental conditions are conducive for a tropical depression to form during the next couple of days while system moves generally west at about 15 mph across the eastern tropical Atlantic Ocean.
* Formation chance through 48 hours: High (70%)
* Formation chance through 5 days: High (90%)

An area of low pressure is expected to form during the next day or two a couple of hundred miles north of the southeastern or central Bahamas as a tropical wave interacts with an upper-level trough. Some gradual development of this system is forecast, and a tropical depression could form later this week while the system moves NNW or north across the western Atlantic.
* Formation chance through 48 hours: Low (30%)
* Formation chance through 5 days: Medium (60%)
