— Flooding is NOT expected today
The atmosphere above Colorado remains in somewhat of a holding pattern today. A very strong ridge, causing record high temperatures west of us, is strengthening but will still remain too far west to completely shut down storm activity. Meanwhile, moisture, as measured by PW, remains unimpressive but enough to cause isolated to scattered storm activity. PW at Grand Junction and Denver measured 0.51 and 0.48 inches, respectively, which is fairly close to seasonal normal for early June in Grand Junction and a bit drier than normal at Denver. Compared to yesterday, today will see (1) little to no organized disturbance overhead, (2) warmer mid-level temperatures by 2-4F, (3) less instability and (4) reduced shear. Overall, we expect a reduction in precipitation coverage, along with a reduced chance of severe weather. However, we still expect to see scattered showers and thunderstorms developing mainly over the higher terrain early this afternoon and this evening. Storms will have a hard time forming at lower elevations today, compared to yesterday. Short pulses of moderate to perhaps briefly heavy rainfall will be possible, but flooding is NOT expected today.
