A Broken Record of 90s

Josh Larson @ 12:00 AM

A sprawling ridge of high pressure aloft, positioned over the center of the country, will allow for an extended period of hazy, hot and humid weather for our area with high temperatures several degrees above average -- in the low to mid 90s.


Forecast Confidence: High Scattered thunderstorms. Today will feature partly to mostly sunny skies and hazy, hot and humid conditions with highs near 90. Expect a 50/50 chance of scattered afternoon and evening thunderstorms, a few of which may be heavy and gusty. Muggy and warm overnight with a stray thundershower and lows in the low to mid 70s.


Forecast Confidence: HighMore widespread thunderstorms. Friday will feature very similar conditions to today, with partly sunny conditions and sultry highs near 90. Look for widespread shower and thunderstorm activity from late afternoon through the overnight hours; again, a few storms may be of the heavy, gusty variety. Overnight lows will be in the mid 70s.

This Weekend

Forecast Confidence: MediumHot & humid but less stormy. A general continuation of today and tomorrow's weather is expected for the weekend, but there will be lowered chances of precipitation. Expect partly to mostly sunny skies with afternoon highs from 90-95 and overnight lows from 72-76. A stray thundershower cannot be ruled out either day but the vast majority of the area should remain dry.


Pattern Overview
Prepare yourself for an extended period of hazy, hot and humid conditions with highs in the 90s. There is very good agreement in computer modeling that a nearly flat jet stream over the next few days will amplify, allowing for an expansive area of high pressure (see image at right) to keep most of the US (including, of course, us) in warmer than normal conditions for at least the next week to ten days; in fact, there are some indications that this heat may linger even longer. As a result, we've got a broken-record forecast on tap for next week.

Next week's forecast
Forecast highs/lows: 91/73 (normal = 88/70)
Forecast precip: Below-normal

Forecast Confidence: Medium-HighIf it sounds like a boring forecast, that's because it is: Expect partly to mostly sunny skies most of the time from next Monday through Friday, with hazy, hot and humid (dew points at or above 70) weather. Most afternoons will feature highs from 90-95, while most overnight periods will feature muggy lows from 70-75. Scattered showers and thunderstorms cannot be ruled out from any day, but, from this vantage point, there does not appear a significant trigger for widespread precipitation.
