Alabama 811 | Know What's Below.

Slightly Less Heat

| June 19, 2015 @ 6:32 am

The upper ridge weakened some yesterday resulting in a slight drop in our afternoon highs, but only a slight drop amounting to 2 or 3 degrees. But glad to have any amount shaved off those highs. As the remnants of Bill continue to trek slowly across the Ohio River Valley today and tonight and into Saturday, we’ll see a continued weakening of the upper ridge with an increase in clouds and scattered showers especially across North Alabama north of the Interstate 20 corridor. But it will still be warm with highs into the lower 90s.

For those headed to the beach, highs will be in the upper 80s, while just inland 90s will be the rule. Showers and storms will be possible as the sea breeze moves inland each day but still plenty of sunshine. Rain chances along the immediate coast are less than 20 percent. Water temperature yesterday afternoon at Perdido Pass in Orange Beach was 86 degrees.

As the remnants of Bill move off the Mid-Atlantic States Sunday, a big upper ridge over the Four Corners area of the Southwest US will build rather quickly across the Central Plains and into the Southeast US. This will bring our chances for showers down with only a few isolated showers possible into next week. It will also bring up the heat once again with highs well into the middle and upper 90s. Heat indices could be reaching near 105, so some heat advisories may be needed.

Severe weather is limited to the North Central US over the next couple of days where the westerlies remain active. There is also a marginal risk in the Ohio River Valley along the track of what’s left of Bill. And the tropics remain quiet with no areas of concern for at least the next several days.

While much of next week is likely to be hot, the GFS continues to carve out a fairly substantial trough over the eastern US as we end June and head into July. This pattern would spell a break in the heat, but it would also put us in a northwesterly flow regime where we would need to keep a wary eye on the development of large clusters of thunderstorms off to our northwest that might impact us. But the trend for a cooler pattern continues to be on the board.

The next Weather Xtreme Video will be posted here on Saturday morning. Stay cool and I hope you get to see a shower today or Saturday.
