Severe-thunderstorm potential appears low on Monday. ...Synopsis... The overall pattern will not change much on Monday. An upper ridge in the West and trough over the central/eastern U.S. will persist amid weak deep-layer flow. A seasonally moist airmass will remain in place east of the Rockies, supporting widespread thunderstorm activity. Much of this activity will likely remain disorganized given weak vertical shear and a little upper support. Some forecast guidance suggests a weak cold front will develop southward across the Canadian Prairies into ND and the Upper Midwest. However, the timing of this feature is uncertain, and may be ill-timed with the diurnal cycle/better thermodynamic conditions. Vertical shear is forecast to remain weak regardless, and confidence is too low to include severe probabilities at this time. Elsewhere, sporadic strong gusts may accompany thunderstorms across the south-central/southeast states where high PW values will be in place, though this activity should remain mostly disorganized, pulse-type convection. ..Leitman.. 07/20/2024 Read more View the full article Quote
