EastCoast NPZ Posted August 6, 2018 Share Posted August 6, 2018 Sick of this humidity. Today is pure grossness. 3.85" for August. Need to get the grass mowed; yesterday's brief pop-up as I was headed out to mow ruined that plan, hoping for better luck today. 8/1 .50" 8/2 .15" 8/3 3.10" 8/5 .10" Link to comment Share on other sites More sharing options...
high risk Posted August 6, 2018 Share Posted August 6, 2018 Can someone please tell me what LWX is doing the last two days? They keep talking about an inversion that will retard convection, but it simply doesn't exist in any of the forecast soundings, and the relative ease with which convection is developing again today (albeit scattered coverage) confirms it's not that tough to initiate convection in this environment. Forcing is weak, which is preventing widespread development, but the idea that we'd have a quiet day is again going to fail. Link to comment Share on other sites More sharing options...

I thought about that, but that's clearly something that would mix out quickly during the heating of the morning hours. Link to comment Share on other sites More sharing options...

North Balti Zen Posted August 6, 2018 Share Posted August 6, 2018 My son responded to my text and confirms it is pouring in Roland Park area (he's at the library). Not anything downtown yet. That's a really tiny but apparently potent cell. Link to comment Share on other sites More sharing options...

yoda Posted August 7, 2018 Share Posted August 7, 2018 Yay From this mornings LWX AFD: .LONG TERM /FRIDAY THROUGH MONDAY/... Weak high pressure will dissipate over the area Friday while an upper-level trough begins to develop over the Great Lakes. The subtropical ridge over the southeastern CONUS will weaken a bit in response to the building trough. Seasonably hot and humid conditions are expected for Friday along with some sunshine with the dissipating high still hanging on. A few showers and thunderstorms are possible due to daytime heating later Friday into Friday evening. At this time, it is most likely that coverage will remain isolated to scattered, but coverage could end up being more widespread if the trough develops quicker or shortwave energy passes through the area in the west to southwest flow aloft. Any convection may wane a bit overnight Friday with the loss of daytime heating. An upper-level trough will dig into the Pacific Northwest Saturday and Sunday and this will cause ridging to develop over the Rockies. The Ridging will cause the trough to our west to develop into a closed upper-level low, causing what is referred to as an Omega Blocking pattern. Guidance seems to be in good agreement with this occurring, but still differs in the exact details of exactly where the upper-level low to our west will cutoff and how strong will it be. Either way, it looks like with the upper-level low to our west this will cause a southwest flow aloft, drawing a return of tropical moisture into our area. Also, surface low pressure may develop nearby or overhead depending on how strong the upper-level low is. The enhanced lift and moisture will cause increasing chances for showers and thunderstorms this weekend, and this pattern is likely to hold into early next week as well. Details are uncertain, but heavy rain is a possibility during this time. Link to comment Share on other sites More sharing options...
