Thereafter the pattern is forecast to amplify considerably, with a large-scale ridge developing over the western US, and a large-scale trough developing over the East. This result will be excessive heat for many locations across the West and long burning periods (relative humidity less than 20%), especially across the Intermountain West. The lack of mid-level flow should preclude strong, gusty winds at the surface. However, given the forecast magnitude of the ridge, hot/dry conditions are likely to cure fuels resulting in elevated fire weather concerns, despite relatively weak surface winds. By late in the week/early next weekend, a cutoff mid-level low will impinge upon the southern portions of the western ridge. The mid-level low will increase mid-level flow and the associated increase in moisture/ascent should be sufficient for thunderstorm development, including dry thunderstorms. Confidence on the timing/evolution of the cutoff low is poor, thus unconditional dry thunderstorm probabilities have not been introduce, but will likely be needed at some point. ..Marsh.. 06/02/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
