We are on STAND-BY for operations on Wednesday, October 24, 2001. The morning GO/NO-GO decision will not be made earlier than 0330 LT (0930Z) for a possible WYKA take-off at 0530 LT (1130Z). The short-term forecast for Wednesday, October 24 promises to be as tough a call as the call for this morning. Several short-waves will pass through the region, along with strong NWerly flow that has produced CLEX target clouds in the past. However, models tend to predict insufficient moisture over LBF and western NE, suggesting any target clouds will form over the Dakotas. These models have not initialized particularly well, and this afternoon's IR images indicate more moisture may enter western NE than predicted. There exists the potential for low-level clouds with precip, and this will have an impact on the final GO/NO-GO decision. If precip should occur over Laramie, it would be in the form of snow and would make travel hazardous for our flight-scientists with high winds in the forecast. This will also influence the final GO/NO-GO decision. In the longer term, strong NWerly flow will persist over western NE on Thursday, under conditions that have brought good CLEX clouds in the past. As of this forecast, there appears to be sufficient moisture for Thursday. A ridge of high pressure will enter the region for the end of the week. Timing on this feature will determine the status of Friday but, so far, the weekend does not look favorable. Curtis/Adam/Larry
