Improving Weekend Weather

ACROSS THE USA: Dangerous heat in the Desert Southwest as record-breaking, dangerous heat will develop this weekend in parts of the southwestern U.S., especially in the deserts where temperatures of 120 degrees will be possible on Sunday through Wednesday. Excessive Heat Warnings and Heat Advisories are in effect across southern Calif., southern Nevada and southern Arizona. These extreme temperatures can be life-threatening.

WEIRD CLOUDS OVER ANTARCTICA: This week in Antarctica, observers have been amazed by the sudden appearance of vivid color in the darkening winter sky. It is not, however, the aurora australis. Instead, icy clouds are forming in the normally-clear stratosphere above the frozen continent, producing an intense iridescence seldom seen at lower latitudes.

FATHER’S DAY: We start tomorrow morning off very nice with with lower humidity levels and many spots in the upper 60s and lower 70s. The rest of the day, expect a good-looking day of weather for all you dads out there. We are forecasting plenty of sun, highs in the upper 80s to near 90 degrees, and lower humidity levels. Any plans you have for dear old dad will have no weather issues, so enjoy.

TROPICAL UPDATE: A tropical wave located near the Yucatan Peninsula is producing cloudiness and disorganized thunderstorm activity from the southern Gulf of Mexico across the Yucatan Peninsula, Belize, and the northwestern Caribbean Sea. A weak surface low pressure system could form over the southern Gulf of Mexico during the next day or so, but only gradual development is expected due to proximity to land and marginally conducive upper-level winds. This system is forecast to move west-northwestward at about 10 mph before it moves inland
early next week.

NEW WORK WEEK: Monday and Tuesday still look dry, with plenty of sunshine and highs in the upper 80s and lower 90s. Nights will be comfortable with temperatures in those soothing 60s. By midweek, moisture begins to return and that means humidity levels are on the way up. We will introduce shower and storms back in the forecast, but very typical of summer, mainly during the afternoon and evening hours. We should see highs in the mid 90s for the second half of the week, with overnight lows in the lower 70s.
