Guys,
Terrible weather conditions, though quite mild and humid, will prevail for most of the day on Friday with that approaching Colorado low, and from the types of clouds seen today, you can tell that its on the move. This is a very complex low, but I won't go into extreme details.
The trajectory of the system has changed in such a way that it will take a ride on the jet stream, move Northward and then take its original Easterly track. Because of this fallback in its prior constant motion/direction, this means that the greatest possiblity of rain/heavy rain could occur in the later afternoon to the early evening along the cold front, according to the precipitation models. Likewise, with the impeding movement, the system will naturally take somewhat longer to exit our region, in which case it won't conclude its business here until early Saturday.
However, unlike other typical Colorado lows, this one lacks somewhat in completing its full development due to the absence of colder air in the West, so things could have actually been a lot worse! On the other hand, the system is still vigorous because there is ample influxes of moisture coming in from the Gulf to sustain its current intensity. As a result, expect the risk of thunderstorms to be greatest in the afternoon to early evening (some of these, if they occur, could produce some loud bangs) in addition to rains. There is again a lot of moisture associated with this, so things will also be a bit humid

and this could indeed serve to cause some of the t-storms out there to reach severe limits(I can't believe I'm stating this kind of scenario and it's almost November!).
To sum up, we have anywhere from an 60-80% chance of rain for the evening hours, along with the risk of thunderstorms, some of which could be heavy should they occur. Winds will be fairly gusty at times, as is the case with vigorous lows, at 25-35 km/h (gusts could be closer 50 km/h) from the South and Southwest, which will shift to the NW after the front comes through. Finally, I suppose we can all appreciate the gorgeous temperature of 17-19 C present at the time.

Note that we could get close to the 25+ mm range, most of which will fall in the afternoon and early evening. The winds are also a concern, so I hope they won't be strong enough to delay the fireworks.
In any case, all I can tell you guys is that all we can hope for is that we get our usual weather-proof fireworks barrier at the time of presentation, as was most prevalent with all the threats this past year, and that things hold off for the 45 minutes provided. I'll give one last report tomorrow before the shows are set to begin, but I'll be looking at radar and satellite imagery to see how things will be processing.
You know the drill, bring your umbrellas and be equipted! I didn't think I'd be storm watching at the end of October...
Trav.
