An unseasonably warm weekend is about to commence over North Texas, with temperatures in the mid to upper 70s. That will come to an abrupt end first thing Monday morning, with the passage of a very shallow, quick-hitting Arctic front. Temperatures Monday will be about 40 degrees colder than those of Sunday. So, get out […]

Atlanta: Thunderstorms and Heavy Rain Tomorrow (Sun 11/23)
For the past week, the global numerical prediction models, including the GFS and ECMWF, have hinted at the potential of a negatively tilted trough digging into the Southeast. They have consistently indicated a strong area of low pressure across the Arklatex propagating off to the northeast into Missouri and Kentucky. Ahead of the low, an […]
DFW: Thunderstorms with Locally Heavy Rain Today (11/22/14)
A vigorous upper-level disturbance is moving into West Texas this morning. The trough axis (and associated forcing) will not move east of the area until tonight.

Lake-Effect Snow: The Physics of Colossal Snow
One of the most awe-inspiring forces of nature is lake-effect snow. The amount of latent energy required to produce the lake-effect convection is astounding, and in some situations, snowfall rates can reach as high as 5 to 6 inches per hour. In this article, we discuss the atmospheric physics, dynamics, and thermodynamics responsible for the […]

DFW: Light Snow Possible Sunday Evening With Reinforcing Shot of Arctic Air
For the past 5 days, I have been closely monitoring a disturbance that will move across North Texas on Sunday/Sunday night. Every meteorologist who has been watching the model data is fully aware of the “accumulating snow” that some of the models have suggested over the past week. One thing that legitimate meteorologists typically do […]
Strong Cold Front To Reach Atlanta Wednesday Evening

At this time, it still appears that the front will move through the Atlanta area during the early-evening hours. After reaching the mid 60s on Wednesday, Atlanta will be 20 degrees colder on Thursday with highs only in the mid 40s. […]
Heavy Rain and Colder Temperatures for DFW on Tuesday 11/4/14
A strong cold front will move through North Texas on Tuesday (11/4/14). The timing of the cold front, and rain amounts may need to be modified with future data. At this time, these are my expectations: Ahead of the front Tuesday morning, temperatures should be 65º to 70º. Temperatures will fall 15 to 20 degrees […]
