FORECAST IN DETAIL

Today the main choice for going out is whether to carry a sweat towel or an umbrella. Humidity levels like this are a bit oppressive but certainly serve for fodder for a decent batch of thundershowers. Tomorrow the tropical moisture comes surging up from the south and, with our weak front still around, thundershowers are likely to be prevalent much of the afternoon/evening. Fortunately, these storms do not look likely to be severe, which is at the top of my list after having a tree smash my car last weekend in those storms! The weekend is a winner as skies clear but humidity hangs tough.

Today (Thursday): The main challenge is to keep from getting totally soaked when out - not from showers, but from the heat and sky high humidity (dew points near 70). Breezes barely register and that is not good news. Highs today jump into the low-to-mid 90s. Thundershowers (50% chance) are not likely to make many inroads until the latter half of the afternoon, probably just in time for rush hour. Confidence: Medium-High

Tonight: Thundershowers should peak in the evening with a 60-70% chance of needing that umbrella wherever you go. Only in the midst of a downpour will there be a breeze. Otherwise, look for muggy and warm conditions through the night. Lows range from the upper 60s to lower 70s. Confidence: Medium

Keep reading for the forecast through the weekend...

Tomorrow (Friday): Thundershowers are likely to get started early thanks to a tropical moisture influx coming up from the Carolinas. The instability continues to grow through the day and there is a whopping 70-80% chance of getting your lawn watered. The good news is temperatures will struggle under the mostly cloudy skies and highs in the mid-to-upper 80s gives us only our second sub-90 degree high for the month. Confidence: Medium-High

Tomorrow night: My guess is that the bulk of the storms follow you poor beachgoers all the way to the coast and leave city dwellers in peace. There will still be a 30% chance of showers in the city and 60% out at the beaches. Evening readings are upper 70s to lower 80s. Clear ing comes, but after midnight. Overnight lows still hold in the upper 60s to lower 70s. Confidence: Medium

A LOOK AHEAD

Saturday dawns with the sun back in control and storms long gone. Humidity levels remain typical for this time of year. The warm up should not be too dramatic but my money is on another 90-degree day...just barely. Highs should end up in the upper 80s to lower 90s. The one important addition to our weather features will be a decent wind from the northwest. The evening is warm with readings in the low-to-mid 80s. Lows should be in the upper 60s to lower 70s. Confidence: High

Sunday is true to its name with very few clouds to be seen. Get the sun screen on and enjoy another summer scorcher with highs mainly in the lower 90s and some mid-90s in those typical hot spots. Humidity is in good supply although bearable as most of us have acclimated by now. Evening readings hold in the mid-to-upper 80s. Lows eventually reach the upper 60s to lower 70s. Confidence: Medium-High

Monday makes even the air-conditioned office look good. Humidity climbs and so do the temperatures under partly sunny skies. Highs reach the low-to-mid 90s. There is a slight 20% chance for an evening thundershower. Confidence: Medium
