Typhoon Tip Posted August 18 Share Posted August 18 there are other ways to do it. I’ve seen spring coastals lay down 4-6” at regional scales. 2010 Mar did three weekends in a row Link to comment Share on other sites More sharing options...

Modfan2 Posted August 18 Share Posted August 18 So, what are the dynamics causing this? Doesn’t seem that humid and wouldn’t think a cold front would dump this much rain? Link to comment Share on other sites More sharing options...
Typhoon Tip Posted August 18 Share Posted August 18 Poorly analyzed warm front situates through the area… Maybe at no-fault to the technology it’s diffused in nature, but it is allowing lift. If you look at the satellite, you can see that there’s a general motion of very warm, humid air coming from southwest and it’s lifting over the boundary. 1 1 Link to comment Share on other sites More sharing options...

WxWatcher007 Posted August 18 Share Posted August 18 Mesoscale Precipitation Discussion 0899 NWS Weather Prediction Center College Park MD 322 PM EDT Sun Aug 18 2024 Areas affected...Western Connecticut Concerning...Heavy rainfall...Flash flooding likely Valid 181922Z - 182252Z Summary...A localized cluster of cells continues to produce very impactful flash flooding over western Connecticut. Cells developing upstream will feed into this complex, which will continue the threat of significant flash flooding. Discussion...Radar continues to track a localized but very efficient cluster of cells which has persisted throughout the morning across western Connecticut. Nearly stationary cell motions and extreme rainfall rates exceeding 3"/hr at times has led to considerable to locally catastrophic impacts across the area, with radar estimates of 7-9" of rainfall noted as of writing. This focused area of extreme rainfall likely focused along a mesolow providing convergence for ascent and enhanced low-level inflow across the region. Upstream of the activity, SFC-850 ALPW and recent ASCAT surface winds also depict a well defined area of confluence embedded within a moist conveyor feeding into the convection. With continued heating, the first signs of cumulus streets and enhanced vertical development are noted upstream, which suggests the area is destabilizing. Thus, additional cells are expected to develop and feed into the area in the presence of the low level forcing. 1 Link to comment Share on other sites More sharing options...

Maybe more cloud condensation nuclei in the air due to the smoke too? Link to comment Share on other sites More sharing options...
