FORECAST IN DETAIL


We are still stuck with our small, atmospheric swirl, over the region. It is this disturbance that’s giving us clouds and periodic rains. Though it isn’t in a hurry, it eventually gets kicked out by our next cold front, so that our work week begins with just a bit more sunshine. By mid-week we should have a better idea how much Isaac-associated rain is enhanced and/or blocked by our cold front, as the cyclone approaches landfall in the Gulf. If you want more rain, you’ll want to root for our work week cold front to slow and/or stall near our area.

Today (Sunday): It’s again very cloudy, with some morning fog/drizzle possible. Showers threaten for much of the day (60% chance), but especially in the morning (70% chance). Some sunshine could crack through the clouds as well, though that may destabilize the atmosphere just enough to pop a few isolated thunderstorms. Temperatures vary with the amount of clouds and morning rain we see—the more clouds, the cooler (around or below 80) our high temperatures. Assuming we get some breaks in the showers and clouds during the afternoon, we may reach as high as the mid-80s. South and east of town may still end up being the favored rain areas as our compact, small, slow-moving system bobs around aimlessly. Confidence: Medium

Tonight: Showers have a 40-50% chance of falling on your location (and outdoor plans) under mostly cloudy skies. I really don’t see the shower threat leaving our area before midnight, but it isn’t a high confidence forecast. Low temperatures just before dawn may briefly bottom out in the range of mid-60s to around 70 (downtown). . Confidence: Low-Medium

Tomorrow (Monday): We remember it is August with juuuust enough sunshine to make us sweat in the muggy air, which easily warms into the mid-to-upper 80s. Perhaps a chance at hitting a 90-degree reading to add to our tally? With light southwest winds transporting a bit of moisture and instability into the region, it seems prudent to place a 20% chance of a few showers or storms popping later in the day. Confidence: Medium

Conditions slowly calm down from any thundershowers or wannabe thundershowers in the area on Monday night, but cloudiness could persist for a while. Low temperatures remain muggy in the upper 60s to low 70s for most of us. Confidence: Medium

A LOOK AHEAD

Tuesday has increased shower and storm chances (30-40% chance) thanks to an approaching cold front. If it remains on schedule at its current forward speed (iffy), we should see our somewhat sunny morning skies turn cloudier by afternoon. High temperatures should hit the mid-80s to low 90s, with lower temperatures possible should showers or storms start earlier in the day, rather than later in the day (before temperatures peak from daytime heating). Confidence: Low-Medium

Wednesday remains iffy because Isaac could actually exert some influence on the atmospheric pattern around the East Coast, so our cold front’s approach could slow or stall nearby. But it should pass through most of the region and net us some sunny skies for most of the day with just a small (10-20% chance) of a shower at this point. But, it remains to be seen how well this front could perhaps protect us from any leftover moisture of Isaac’s remnants, as it moves northward. For now, high temperatures in the 80s still appear probable. Confidence: Low
