Event total here: 1.99". Enough but not excessive. While some slight long term dryness is still going on the drought up in my area is essentially over. July will end up being a very wet month up this way and for the sub forum with maybe a few exceptions. Just need to keep up at least normal rainfall next several months to keep from slipping back into dryness. Not sure my grass has ever been greener heading into August.

Total rainfall from yesterday’s event-2.12”. -
Upslope not nearly as big factor this time of year, simply b/c low-level winds from the SE, E, or NE are not as strong, and fetch is much less. Ever notice summer low pressure areas are smaller than the cool season counterparts? Well, there is reason for that and thus you can't treat things synoptically all the same in the summer. Convection plays a much larger role in the summer, so that messed w/ things are well. Swaths from training regardless of topography.

Chester County PA - Analytical Battle of Actual vs. Altered Climate Data
chubbs replied to ChescoWx's topic in Climate Change
Extended the stat analysis to the 1970s to include the West Chester move. Two comparisons were made: individual years using 1972 minus 1945 as a metric, and a 5-year average using 1971-75 minus 1941-45 as a metric. The results are the same for both metrics: the Chester County COOPs are significantly different statistically from the non-Chesco stations. As was the case for the 1950s there is no overlap between the move and non-move stations. The Chester County COOPs have spurious cooling of over 2F. This analysis and the one above provide strong evidence that the larger NCEI bias adjustments are very robust statistically. This analysis also shows the problems with AI. As Don stated above AI is handy for an initial screening; but, AI is unlikely to give a complete and accurate answer to a complex problem.
