Rain Developing
* Rain is beginning to develop across parts of Arkansas, and these showers will continue developing and moving east. As this occurs, even more rain will fill in across Louisiana and eventually Mississippi, as warm, moist air is lifted over a cool airmass in place near the surface.* The next few days look mostly wet. It will not rain all week, but periods of rain will be the rule rather than the exception in coming days. It will be a cold rain, as highs stay in the 50's for most of this week.
* Weekend cooldown? The latest computer model guidance seems to back off a bit on the cold air intrusion forecast for this weekend. But, we will stick to the idea of a turn to cooler weather. That being said, we will probably raise our forecast high a degree or two while things sort themselves out a bit.
* What's ISENTROPIC LIFT? Much of the rain this week is in response to what we call "isentropic lift." To find out more about this efficient rain (and sometimes snow) producer, check out the following websites, packed with great info for REAL weather fans:
