I don't have much time to write about this weather system today, but it is getting me excited for next week. Here is what the NWS office in STL has to say about it:
...WINTER STORM POSSIBLE NEXT WEEK...
AN ARCTIC HIGH PRESSURE SYSTEM WILL LOCK A SUBFREEZING AIRMASS OVER THEBI-STATE AREA THIS WEEKEND...AND THESE COLD TEMPERATURES WILLPERSIST THROUGH THE MIDDLE OF NEXT WEEK. SOUTHERLY FLOW FROM THEGULF OF MEXICO WILL DEVELOP ON MONDAY NIGHT IN RESPONSE TO AWEATHER SYSTEM THAT WILL MOVE FROM THE DESERT SOUTHWEST INTO THEMIDWEST DURING THE MIDDLE OF THE WEEK. MOISTURE FROM THE GULF OFMEXICO WILL BE PUSHED INTO THE VERY COLD AIRMASS OVER THE BI-STATEREGION BY THIS SOUTHERLY FLOW. SNOW...SLEET...AND FREEZING RAINARE LIKELY ACROSS THE REGION...AND THERE IS THE POTENTIAL FORSIGNIFICANT ICE AND SNOW ACCUMULATIONS ON MONDAY NIGHT ANDTUESDAY...POSSIBLY CONTINUING FURTHER INTO THE WEEK.
Since this system is still in the Pacific Ocean, there is still some uncertainty as to the track/speed/strength of the storm. It is worth watching, and I'll post more as the system gets closer.
